In the Volume of Cylinders, Cones and Spheres Section, if a cylinder has a radius of 3 and a height of 8, check all that apply.

V=(πr^2)h

V=2πrh

V=1/3(πr^2)h

V=72π

V=48π

V=24π

V=226.2

V=150.8

V=75.4

V= πr²h

V= 72π

V= 226.2

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, a cylinder

Given data

Radius r of cylinder 3

Height h of cylinder 8

We know that the volume of a cylinder is given as

V= πr²h

Substituting our given data we have

V= π3²*8

V= π9*8

V= 72π

V= 226.2

q1 a person or thing situated away or detached from the main body or system. a cluster is a a mash of many things.

q2 do

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
