What is the volume of the right prism?
15in
17in
10in
8in
a. 1200 in3 <--- ? A
b. 600 in3
c. 400 in3
d. 50 in3
The 17 doesn't matter I believe. It is labled inside the prism on the grey which is the opposite side as the 15. So I just did 15 x 10 x 8. Plus if I use 17 it would have be 2040 and that's not an option. Unless Im wrong..

SORRY i forgot to put math
1 is right.
2 -- can't tell because we don't know the diameter
3 -
The volume of cylinder is found using this formula: V = pi * r^2 * h
You didn't use the radius squared. You used the diameter.

for 2 it just has a line with a T and a line with 17cm.
for 3 How do I find the radius? is it C?

V= 30 X 15 ^2 * 30 = 21,195
I got it lol
the radius is half of 30 which is 15
I got it lol
the radius is half of 30 which is 15
Yes! :-)
and for 2 the diameter is 17cm
8.5 is the radius of 17.
So I put 8.5 x 2 x 3.14 = 53.38 and rounded is 53.4?
