Question

find the area circular path is the radius of the outer circle is 70cm and the radius inner circle is 56 cm​

Answer 1

Answer:
5,538.96 square m.
Step-by-step explanation:

Outer radius = 70 cm

Area of outer circle = π r²

                               =  3.14 × $(70)^2$

                               =   15,386

Inner radius = 56cm
Area of inner circle= π r²

                               =  3.14 × $(56)^2$
                               = 9,847.04

Thus the area of circular ring = Area of outer circle - Area of inner circle

                                 = 15,386-9,847.04
                                 = 5,538.96
Hence the area of circular ring is 5,538.96 square m.
