Question

6. Find the radius of the circle whose area:
is (take r = 3.14):
a) 530.66 m² b) 706.5 cm? c) 200.96 m2​

Answer 1

Answer:

Area of Circle = 200.96 sq cm

\pi {r}^{2} = 200.96πr

2

=200.96

3.14 \times {r}^{2} = 200.963.14×r

2

=200.96

{r}^{2} = \dfrac{200.96}{3.14}r

2

=

3.14

200.96

{r}^{2} = 64r

2

=64

{r}^{2} = \sqrt{64}r

2

=

64

r = 8

Radius = 8 cm

Circumference of Circle = 2πr

= 2 × 3.14 × 8

= 50.24

Radius = 8 cm

Circumference of Circle = 50.24 cm
