How do u calculate the surface area of a cylinder?

For a cylinder there is 2 kinds of formulas the lateral and the total. the lateral surface area is just the sides the formula for that is 2(pi)radius(height). the formula for the total surface area is 2(pi)radius(height) + 2(pi)radius squared.

What are the units for surface area of a cylinder?

Just like ordinary area, the units are the squares of the units of length (that is, if a shape’s sides are measured in meters, then the shape’s area is measured in square meters).

How do you find the height and radius of a cylinder given the surface area?

Given height and surface-area-to-volume ratio: r = 2 * h / (h * SA:V – 2) , Given volume and lateral area: r = 2 * V / A_l , Given base area: r = √(A_b / (2 * π)) , Given lateral area and total area: r = √((A – A_l) / (2 * π)) .

Which of the following is the surface area of the right cylinder below 8 3?

The answer is 252 pi units.

Which of the following formulas would find the lateral area of a right cylinder?

Lateral surface area of right cylinder = 2 * π * radius * height . Formula for LA = 2πrh. Therefore, Lateral surface area of right cylinder = 2 * π * radius * height.

What is the surface area of the right cone below?

The answer is 54pi. Hope this helped!

What is the volume of this right cone?

Volume of a cone: V = (1/3)πr2h.

How do you calculate drop by height?

Free fall means that an object is falling freely with no forces acting upon it except gravity, a defined constant, g = -9.8 m/s2. The distance the object falls, or height, h, is 1/2 gravity x the square of the time falling.

How do you find how long it will take something to hit the ground?

Measure the distance the object will fall in feet with a ruler or measuring tape. Divide the falling distance by 16. For example, if the object will fall 128 feet, divide 128 by 16 to get 8. Calculate the square root of the Step 2 result to find the time it takes the object to fall in seconds.

What is the formula for maximum height in projectile?

h = v 0 y 2 2 g . This equation defines the maximum height of a projectile above its launch position and it depends only on the vertical component of the initial velocity. A rock is thrown horizontally off a cliff 100.0 m high with a velocity of 15.0 m/s.

What is acceleration at maximum height?

Answer: 0 m/s. The instantaneous speed of any projectile at its maximum height is zero. Because gravity provides the same acceleration to the ball on the way up (slowing it down) as on the way down (speeding it up), the time to reach maximum altitude is the same as the time to return to its launch position.

How do you find the initial height of a projectile?

Solution: Choose the formula h = -16t2 + v0t + h0. The initial velocity, v0 = 200 ft/sec and the initial height is h0 = 0 (since it is launched from the ground). Formula: h = -16t2 + 200t + 0.

What are the formulas for projectile motion?

Projectile motion equations

• Horizontal velocity component: Vx = V * cos(α)
• Vertical velocity component: Vy = V * sin(α)
• Time of flight: t = 2 * Vy / g.
• Range of the projectile: R = 2 * Vx * Vy / g.
• Maximum height: hmax = Vy² / (2 * g)

How do you calculate the flight time of a projectile?

To define the time of flight equation, we should split the formulas into two cases:

1. Launching projectile from the ground (initial height = 0)
2. t = 2 * V₀ * sin(α) / g.
3. Launching projectile from some height (so initial height > 0)
4. t = [V₀ * sin(α) + √((V₀ * sin(α))² + 2 * g * h)] / g.

What are the 2 types of projectile motion?

In a Projectile Motion, there are two simultaneous independent rectilinear motions:

• Along the x-axis: uniform velocity, responsible for the horizontal (forward) motion of the particle.
• Along y-axis: uniform acceleration, responsible for the vertical (downwards) motion of the particle.

What is the most important factor in projectile motion?

What is projection speed? Take off Velocity. (This determines height and horizontal length of trajectory (range)). This is the single MOST IMPORTANT factor affecting the range of projectile.

What are the 3 types of projectiles?

Three types of projectiles— the bullet, the round ball, and shot—are used in muzzleloaders.

What are the factors that affect a projectile motion?

Factors affecting the flight path of a Projectile are:

• Gravity.
• Air Resistance.
• Speed of Release.
• Angle of Release.
• Height of Release.
• Spin.
