A cylinder has a diameter of 10 units. Its radius is ____ units. Of its height is _______ twice its radius, its height is units.

SpyIntel [72]

Answer:

Height is 10 units

Volume is 785 cubic units

Step-by-step explanation:

We are given;

Diameter of a cylinder as 10 units

But, radius = d/2

= 5 units

Height is twice its radius,

Thus, Height = 10 units

We can get the volume;

Volume of a cylinder = pir²H

Taking pi to be 3.14

Then;

Volume = 3.14 × 5²× 10

= 785 cubic units

Thus, the volume of the cylinder is about 785 cubic units

What is the volume of the pyramid 7x7x8

dolphi86 [110]

Answer:

The volume of the pyramid is $130\frac{2}{3}\ units^{3}$

Step-by-step explanation:

we know that

The volume of the pyramid is equal to

$V=\frac{1}{3}BH$

where

B is the area of the base

H is the height of the pyramid

In this problem we have a square base

$B=7^{2} =49\ units^{2}$

we have

$H=8\ units$

substitute

$V=\frac{1}{3}(49)(8)=\frac{392}{3}\ units^{3}$

Convert to mixed number

$\frac{392}{3}=\frac{390}{3}+\frac{2}{3}=130\frac{2}{3}\ units^{3}$
