Question

find the radius of the circle whose area is 176​

Answer 1

Answer:

28

Step-by-step explanation:

Area of circle= 2 ×22/7×r

176= 2×22/7×r

176×7/2×22=r

4×7=r

r=28

Answer 2

Answer:

HERE IS YOUR ANSWER

Step-by-step explanation:

Let the radius of the circle be R.

now,

area of the circle

$area of \: the \: cicle = \pi {r}^{2}$

so

$176 = \pi {r}^{2}$

$\sqrt{176 \times 7 \div 22 = r}$

$\sqrt{7 \times 8 = r}$

$\sqrt{56 = r}$

$r = 2 \sqrt{14}$
