Answer:
Radius of the base is 4 cm.
Step-by-step explanation:
Given
.The curved surface area of a right
circular cylinder of height 21 cm is
528 cm.
To find E
The radius of the base of the
cylinder.
Solution
Let the radius of the cylinder be r cm.
2Trh = 528
22
Xrx21 = 528
7
2x
2x 22 x rx 3 528
132r = 528
= 4
r
Therefore the radius of the cylinder is 4
cm.
Additional Info
Volume of cylinder = mrh
.T.S.A of cylinder = 2TTrh + 2Tr
Volume of cone = s Tmr-h
.C.S.A of cone = Trl
.T.S.A of cone = TTrl + Tr
.Volume of cuboid = | x bxh
