Question

The area of this circle is 50.27 m2 to 2 decimal places. What is the diameter of the circle?

Answer 1

d = 7.98m

Explanation:

Area of a circle = 50.27 m²

πr² = 50.27

`(22)/(7)*r^(2)=50.27\\\\ r^(2) = (50.27*7)/(22)\\\\ r^(2) = 15.995\\\\ r = √(15.995)\\ r = 3.99`

d = 2* 3.99 = 7.98 m
