Question

Can anyone help me with this it would be great.

Answer 1

1. The error is that he made the radius a diameter.
2. The circumstances is 150.8571428 m

Explanation:

π = 22/7 or 3.14

Circumference= diameter × 22 / 7

= 2 × radius × 22 / 7

= 2 × 24 × 22/ 7

= 48 × 22 / 7

= 48 / 1 × 22 / 7

= 1056 / 7

= 150.8571428 m

Answer 2

11. The student put 24 as the diameter instead of the radius.

12. 48 pi

Explanation:

The formula for the circumference of a circle is c = pi x diameter.

However, the question says that the radius is 24m, not the diameter.

To fix it, all you need to to is double the radius to get 48m for the diameter.

48 x pi = 48 pi
