volume of cylinder=h pi r^2
r=15
h=45
aprox pi to 3.14 since the answers dont inlcud pi
v=45 itmes 3.14 times 15^2
v=45 times 3.14 times 225
v=31,792.5 cu. ft
answer is B
area=pir^2
diameter=2radius
diameter/2=radius
diameer=10
10/2=raiuds=5
area=pi times 5^2
aprox pi to 3.14 since answers not given in pi
area=3.14 times 25
area=78.5 in^2
answer i C
5. B 31,792.5 cu. ft.
8. C 78.5 square inches
