The height of a cylinder is 15 cm and curved surface area is 1320 cm2

1.	The height of a cylinder is 15 cm and curved surface area is 1320 cm2 .find its radius
Answer» Step-by-step explanation: Given: h=15cm CSA=1320 cm^2 we KNOW that the FORMULA for the csa of cylinder is 2πrh So 2πrh=1320 cm^2 => 2×22/7×r×15=1320 =>660/7×r=1320 =>r=1320×7÷660 =>r=14 .·. The RADIUS of the cylinder is 14 cm

The height of a cylinder is 15 cm and curved surface area is 1320 cm2 .find its radius

Answer»

Step-by-step explanation:

Given: h=15cm

CSA=1320 cm^2

we KNOW that the FORMULA for the csa of cylinder is 2πrh

So 2πrh=1320 cm^2

=> 2×22/7×r×15=1320

=>660/7×r=1320

=>r=1320×7÷660

=>r=14

.·. The RADIUS of the cylinder is 14 cm
