Let r cm be the radius and h cm be the height of the cylinder. It is given that the ratio of r and h is 2:3, so h = 1.5r
The volume of the cylinder (V) is 1617 cm3.
So, we can find the radius and the height of the cylinder from the equation given below:
V= πr2h
1617 = πr2h
1617 = πr2(1.5r)
r3 =343
r = 7 cm and h = 10.5 cm
Total surface area = 2πr2+2πrh
ā =
Hence, the total surface area of the cylinder is 770 cm2.
