## What is the volume of the sphere round to the nearest tenth?

1 Answer. The volume of the sphere is 5061.90π (rounded to the nearest tenth and leaving it in term of pi) or (rounded to the nearest tenth and not leaving it in term of pi).

## What is the volume of the sphere use 3.14 for PI and round to the nearest hundredth when necessary?

Use 3.14 for pi and round to the nearest hundredth when necessary. 50.24 m³

## How do you memorize the volume of a sphere?

You do need to be more specific, the volume of a sphere is V = 4/3 π r^3, it does not need to be related to a cylinder. So if you know the radius, you can calculate the volume. The volume of a cylinder with the same radius and with a height of 2r (since it would be the diameter across) would be V = π r^2 h = 2π r^3.

## How do you find the volume of a sphere without a calculator?

Use the circumference formula (C=2πr) and rearrange it to solve for the radius (r=C/2π). Once you have the radius (r), you can use that value in the volume of a sphere formula (V = 4/3πr³).

## What is the definition of volume and capacity?

Volume is the amount of space a container or object occupies. Capacity is the amount of water required to fill the fish tank (ml or L). Example. Volume is the space the tank and water take up. The most common unit of volume is centimetres cubed (cm3).

## Why do we need volumes in Kubernetes?

It supports any or all the containers deployed inside the pod of Kubernetes. A key advantage of Kubernetes volume is, it supports different kind of storage wherein the pod can use multiple of them at the same time.

## What is volumes in Kubernetes?

A Kubernetes volume is essentially a directory accessible to all containers running in a pod. In contrast to the container-local filesystem, the data in volumes is preserved across container restarts.

## How do I use volumes in Kubernetes?

To use a volume, specify the volumes to provide for the Pod in . spec. volumes and declare where to mount those volumes into containers in . spec.

## What is PV in Kubernetes?

Kubernetes persistent volumes by example. A persistent volume (PV) is a cluster-wide resource that you can use to store data in a way that it persists beyond the lifetime of a pod.

## What are the specs declared in deployment?

Under spec, we declare the desired state and characteristics of the object we want to have. For example, in deployment spec, we would specify the number of replicas, image name etc. Kubernetes will make sure all the declaration under the spec is brought to the desired state. Spec has three important subfields.

## How do I get rid of persistent volume?

To securely delete the Persistent Storage, you have to securely delete the entire USB stick, which is a much slower operation.

1. Start Tails from the USB stick on which you want to delete the Persistent Storage.
2. Choose Applications ▸ Tails ▸ Delete persistent volume.
3. Click Delete.

## How do you make a persistent volume?

Creating a persistent volume Change the storage capacity to your desired amount. The above example will create a 10 GiB volume. Replace with the desired ID of the volume.

## What is persistent volume claim?

To provide a durable location to prevent data from being lost, you can create and use persistent volumes to store data outside of containers. A persistent volume claim (PVC) is a request for storage, which is met by binding the PVC to a persistent volume (PV).

## What is the difference between persistent volume and persistent volume claim?

So a persistent volume (PV) is the “physical” volume on the host machine that stores your persistent data. A persistent volume claim (PVC) is a request for the platform to create a PV for you, and you attach PVs to your pods via a PVC.

## What is Storageclassname in Kubernetes?

A StorageClass provides a way for administrators to describe the “classes” of storage they offer. Different classes might map to quality-of-service levels, or to backup policies, or to arbitrary policies determined by the cluster administrators. Kubernetes itself is unopinionated about what classes represent.
