Question

A cylinder has height 15 and its curved surface are is you 471sq.cm find radius of its base​

Answer 1

Answer:

Step-by-step explanation:

CSA of cylinder = 2 *22/7*r*h

471 =2*22/7*r*15

r= 1099/220 cm ans

Answer 2

Curved surface area of Cylinder = 471 cm^2

Height of the cylinder = 15 cm

so according to the question,

2πrh = 471

2×22/7×r×15 = 471

r = 4.99 cm

so the radius of the cylinder is 4.99 cm
