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

I need the answer asap

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:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

8
