Question

If the radius of the circle is R. Find the area of the circle.

• A. 42 cm²
• B. 30 cm²
• C. 35 cm²
• D. 38.5 cm²

Answer 1

Answer: (D)

38.5 cm²

We are asked to find the area of the circle. The equation for the area of the circle, A = $\pi \times R^2$

= $\left(\frac{22}{7}\right)\times {3.5}^2$

= 38.5 $c{m}^2$

The area of the circle is 38.5 $c{m}^2$.
