Question

Estimate the area of the circle to the nearest unit.

Answer 1

48 cm²

Explanation:

Area of circle formula: A = πr²

= π (d/2)²

= 3.14 * (4)²

= 50.24

The area of the circle is closest to Option D, 48 cm²

Answer 2

Step-by-step explanation: We know that ,

Area of circle =πr² and

r = radius of circle.

Now,

Diameter of circle =56 cm [given]

So, radius of circle=D/2=56/2

Radius of circle=28

Now,

Area of circle=πr²

Area of circle=22/7 ×(28)² [π=22/7]

Area of circle=22×4×28

Area of circle=2464cm²

Hence, Area of circle is 2464cm²
