Question

please solve this problem

find the diameter of the circle whose
area=962.5cm2

Answer 1

Area of a circle

$\pi \: {r}^{2} = 962.5 \\ \\ \frac{22}{7} \times {r}^{2} = 962.5 \\ \\ {r}^{2} = \frac{962.5}{3.14} \\ \\ {r}^{2} = 306.6 \: (approx) \\ \\ r = 17.51 \\ \\ diameter \: = 17.51 \times 2 = 35cm \: approx$

Answer 2

Answer:

35 cm

Step-by-step explanation:

We know that,

$\pi r^{2} = Ar(Circle)$

πr²=962.5

r²=962.5×7÷22

r²=306.25

r=√306.25

r=17.5

d=2r

d=2×17.5

d=35cm
