Question

The radius of a circle is $\frac{7}{\pi }$ cm. Then the area of the circle in $c{m}^2$ is ?

• A. 154
• B. 49/π
• C. 22
• D. 49

Answer 1

Answer: (B), (D)

The correct options are
B

49/π

D

49

$A=\pi r^2$

$A=\pi \times \frac{7}{\pi }\times \frac{7}{\pi }=\frac{49}{\pi }=\frac{7^3}{22}$
