Question

The area, A, of a circle with radius r is given approximately by the formula A = 3.14 r2.
What is the area of a circle of radius 10 cm? Give your answer to the nearest square cm.

Answer 1

Here, Radius given is 10cm

Therefore, Area of a circle = 2pie*r^2

                                            = 2*3.14*100

                                            = 2*314

                                            = 628 cm^2

Answer 2

Answer:

A = 3.14 x r^2

A=3.14 ×10^2

A=314 sq. cm
