Look at the picture.

The formula of the volume of a cylinder:

$V_C=\pi r^2H$

We have:

$d=6m;\ d=2r\to r=3m\\H=25m$

Substitute:

$V_C=\pi\cdot3^2\cdot25=225\pi\ m^3$

The formula of the volume of a sphere:

$V_S=\dfrac{4}{3}\pi r^3$

We have a hemisphere, therefore the formula of the volume is:

$V_H=\dfrac{1}{2}V_S=\dfrac{1}{2}\cdot\dfrac{4}{3}\pi r^3=\dfrac{2}{3}\pi r^3$

We have:

$r=3m$

Substitute:

$V_H=\dfrac{2}{3}\pi\cdot3^3=\dfrac{2}{3}\pi\cdot27=2\pi\cdot9=18\pi\ m^3$

The volume of a silo:

$V=V_C+V_H\to V=225\pi+18\pi=243\pi\ m^3\approx243\cdot3.14\approx763\ m^3$

Answer: 763 m³.

What is the radius of a circle whose circumference is 16π?<br> A. 32π<br> B. 16<br> C. 8 π<br> D. 8

Paladinen [302]

Answer:

Step-by-step explanation:

Remark

The circumference of a circle is 2 * pi * r

Given

The circumference (C) = 16 * pi

Solution

2 pi r = 16 pi Divide by 2*pi

r = 16 pi / (2*pi)

r = 8
