Question

Hello! I need help with 2 questions, PLEASE ANSWER THEM BOTH OR DO NOT ANSWER LET OTHERS DO IT.

1) What is the exact volume of the cylinder? (FIRST picture)
1280π in3
640π in3
10,240π in3
25,600π in3

2) What is the approximate volume of the cylinder?

Use 3.14 for π.

4000 cm3
1143 cm3
572 cm3
12,561 cm3

Answer 1

v=hpir^2

I will assume that the first one is the one with radius 16 and height 40
2nd is radius 7 and height 26



1. v=hpir^2
v=40pi16^2
v=40pi256
v=10240pi cubic inches
3rd option





2.
v=hpir^2
v=26(3.14)7^2
v=26(3.14)(49)
v=1274(3.14)
v=4000.36 cubic cm
1st option
