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
