Answer: 10380cm^3

Explanation:

Find the volume of half cylinder:

V = (pi x r^2 x h)/2 (I use pi = 22/7 for simplifying)
V = 22/7 x 6^2/2 x 35
V = 22/7 x 36/2 x 35
V = 22/7 x 35 x 18
V = 22 x 5 x 18
V = 1980cm^3

Find the volume of the rectangle:

V = 20 x 35 x 12
V = 240 x 5 x 7
V = 1200 x 7
V = 8400cm^3

Find the volume of the whole shape:

V = 1980 + 8400
V = 10380cm^3

The circumference of a circle is 12 inches. What is the radius

IceJOKER [234]

Greetings!

"The circumference of a circle is 12 inches. What is the radius?"...

We can use the formula to find the circumference of circle to solve this:
 $2 \pi r$

Input the information we know:
 $2 \pi r=12$

Solve for r, using the properties of equality:

Simplify.
 $6.28r=12$
Divide both sides by 6.28
 $(6.28r)/6.28=(12)/6.28$ 
Simplify.
 $r=1.91$

The radius is 1.91cm long.

Hope this helps.
