Question

A circle has a diameter of 8. What is the area in terms of π?

I need the answer asap

Answer 1

Answer:

50.24²

Step-by-step explanation:

Okay, so the formula for the area of a circle is π x radius² and we're just going to use 3.14 for π so:

We first have to find the radius, the radius is half the diameter:

8 ÷ 2 = 4

So 4 is our radius

4² = 16

3.14 x 16 = 50.24

So, the area of the circle is 50.24²

hope this helps:)

Answer 2

Area is approximately 50.27

Formulas:
A=pi r^2
D=2 r

When solving for A:

A=1/4pi d^2 = 1/4*pi*8^2 which is approximately 50.26548


ANSWER: approximately 50.27
