Question

Find the area and the circumference of a circle with diameter 8yd

Answer 1

25.12

Explanation:

c = 2 pi r

d = 8 so r = 4

c = 2 * 3.14 * 4

c = 25.12

Answer 2

Explanation:

Given

Diameter (d) = 8 yd

radius (r) = d/2 = 8/2 = 4

Now

Area = π * r²

= 3.14 * 4²

= 50.24 yd²

Circumference

= π * d

= 3.14 * 8

= 25.12 yd
