Question

- From a square metal sheet of side 28 cm, a circular sheet is cut ofl. Find the a
largest possible circular sheet that can be cut. Also find the area of the remaning sheet?​

Answer 1

Answer:

196$\pi$ cm² and 168 cm²

Step-by-step explanation:

Because the width of the square is 28 cm, the max diameter is also 28 cm.

Using the formula; Area = $\pi$r²

The radius is half the diameter, so the radius is 28 ÷ 2, r = 14

1. The Area of the circle; $\pi$ x 14² = $196\pi$ cm²

2. The Area of the square; 28 x 28 = 784 cm²

3 The remaining area is the area of the square minus the area of the circle;

   784 - $196\pi$ = 168.247 cm²

4. Round to 3 significant figures and you get 168 cm²
