Answer:

75π is the answer

Explanation:

In term of pie is solving without multiplying with pie which is 3.14

A=πr2 x H

1) leave π alone solve for r2

The radius is 5 so 5 squared is 25 or 5x5=25

2) Just multiply 25 times the height which is 3 with pie

25x3=75

75π is the answer

Hopes this helps!

Answer:

Explanation:

The formula of a volume of a cylinder:

$V=\pi r^2H$

r - radius

H - height

From the pictue we have r = 5in and H = 3in. Substitute:

$x=\pi(5^2)(3)=\pi(25)(3)=75\pi\ in^3$

$\pi\approx3.14$

Therefore

$x=(75)(3.14)=235.5\ in^3$
