Question

the CSA of a cylinder 5280 sq.m and it's height is 40m. find its radius​

Answer 1

Answer:

∴The radius of the cylinder is 2.10 cm.

Explanation:

Height = 40m

C.S.A of Cylinder = 5280$m^{2}$

2πrh = 5280

2 x  × 3.14 × r × 40 = 5280

6.28 × r × 40  = 5280

251.2 × r = 5280

r      =   $\frac{5280}{251.2}$

r = 2.10m

∴The radius of the cylinder is 2.10 cm.
