Question

Find the diameter and circumference of the circke if its area is 6.16m²

Answer 1

Answer:

πr²=6.16

r=√(6.16/π)

then diameter is 2*r that means 2*√(6.16/π).

and circumference is 2*π*r that means

2*π*√(6.16/π)

2*√π*√6.16

Answer 2

Answer:

Diameter= 2.8 m, circumference= 8.8m

Step-by-step explanation:

area of circle = πr²

6.16 = 22/7 r²

r²= 6.16*7/22 = 1.96

r = ± √1.96 = 1.4 m.

circumference of circle = 2πr = 2*22/7*1.4 = 8.8 m

Diameter of Circle = 2r = 2*1.4 = 2.8 m
