Question

A circular park has diameter 42m. A 7m road runs around the park. Find the area of the road.

Answer 1

Answer:

923.65

Step-by-step explanation:

Diameter = 42m

Radius = 42/2 = 21m

Road Around The Park = 7m

Circumfrence of the park = 2πr

                                          = 2 x 3.14 x 21

                                          = 131.95m

Area of Road around the Park = 131.95 x 7

                                                  = 923.65 m.sq

I Hope This Would Help You !!

Answer 2

Answer:

Step-by-step explanation:

Diameter =42

Radius=42÷2

=21m

Road around the park= 7m

Circumference =2pi r

=2×22/7×21

=2×22×3

=132m

Area of the road around the park =132×7

=924m.sq
