Q # 1 please help solve. as soon as possible

Answer 1

The formula for the volume of a cylinder is equals to πr^2*h

Given:
 radius=7 inches (radius = diameter/2 = 14/2 = 7)
and the height =18 inches

Substitute:Volume = π*7^2*18= 882π= 2771 in.^3 

SO the answer would be the third option which is 2771 in.^3 

Answer 2

The volume of a cylinder is given by the formula πr^2*h, so if the radius in this case is 7 inches (radius = diameter/2 = 14/2 = 7) and the height is 18 inches, then we can substitute these values into the formula above to get:

Volume = π*7^2*18
= 882π
= 2771 in.^3 (to the nearest cubic unit)
