Question

A circle has radius 50 cm. Which of these is closest to its area?



1: A
2: B
3: C
4: D

Answer 1

Answer:

C) 7854 cm²

Step-by-step explanation:

The formula for the area of a circle is A = πr²

Now just plug in the numbers

A = π (50²)

A = 2500π

Let's say pi is 3.14

A = 2500(3.14)

A ≈ 7850

The closest answer to this answer is C: 7854
