Question

The inner curved surface area of a well is 792 m2

and radius of its base is 21 m. Find its height PLEASE HELP PLEASEEE​

Answer 1

Answer:

C.S.A of well (like as Cyliender )=792m^2

height=h

2.pie.r.h=792

2×22/7×21×h=792

2×22×3×h=792

h=792/(2×22×3×)

h=(2×2×22×3×3)/(2×22×3)

h=2×3

height =6mt.
