Question

What is the area of a circle with diameter 12 inches?

144pi in2

6pi in2

12pi in2

36pi in2 @Venny

Answer 1

Okay the area of a circle is given by the formula \(\Large\ A=\pi(r)^2\)
but we are given the diameter and \(\large\ d=2*r\)
so if d=12, what is r?

Answer 2

3.14?

Answer 3

Nooo, divide 12 by 2, 3.14 is pi

Answer 4

6

Answer 5

lol srry

Answer 6

b?

Answer 7

No, you forgot to plug it into the formula first
\(\Large\ A=\pi(6)^2\)

Answer 8

6x2=12

Answer 9

37.68

Answer 10

Hmm not quite \(\large6^2\) means you need to do \(\large6*6\) because you have to multiply the number times itself

Answer 11

36 is the answer?

Answer 12

Yes \(36\pi\)
