Question

Find the area of a circle that has a diameter of 11 inches. Round your answer to the nearest hundredth.

Answer 1

A=3.14*5.5^2

Answer 2

π D = 11
D=11/π
D = 3.501408
D/2 = r
r = 1.7507
π r^2 = 9.63

Answer 3

95.033

Answer 4

But why would it not be 95.03

Answer 5

Yes it would be 95.03...Sorry about that :(

Answer 6

So it is 95.03 not 9.63

Answer 7

Yes.

Answer 8

no she made a mistake, to find the diameter you need to multiply π by D to get diameter instead she multiplied D * 2 to find diameter which is whrong\

Answer 9

This is the formula to find the area of a circle:
\[A =πr^2\]

Answer 10

5.5 is the radius.

Answer 11

nope
the radius is half the diameter
And the diameter is Circumference divided by π

Answer 12

I'm confused

Answer 13

oh wait
sorry I was reading two problems at the same time, PinkSohire is actually right

Answer 14

I know that...the diameter is 11 so to get the radius, you have to divide by 2.

Answer 15

yeah sorry I thought it said circumfernce

Answer 16

Oh okay :)

Answer 17

So 95.03 is correct

Answer 18

Yes.
