Question

Find the diameters of the circles whose areas are given below. (Round off the decimals to the nearest integers)

(a) 706.5 m²
(b) 254.34 cm²
(c) 379.94 mm²
(d) 3140 m²

​

Answer 1

Answer:

Step-by-step explanation:

Formula for area is A = Πr^2

 A = 706.5

So, 706.5=Πr^2

706.5/Π = r^2

r^2 = 225

So, r = 15m.
