Question

There is a circular pool in the backyard with an approximate area of 113 square inches. What was the diameter?

Answer 1

\[113= \pi r ^{2}= \pi (d/2)^{2}\]
\[113= \frac{ \pi d^{2} }{ 4 }\]
you can solve for d now.

Answer 2

Area of a circle is\[A=\pi \times r ^{2}= \pi \times (\frac{ d }{ 2 })^{2}\]

Answer 3

still dont understand
1111111111:{

Answer 4

ok

Answer 5

here, r is the radius
d is the diameter.
we know that, radius is the half of the diameter of the circle.
r=d/2

Answer 6

\[113= \pi \times \frac{ d ^{2} }{ 4 }\]

Answer 7

\[d ^{2}=\frac{ 113 \times 4 }{ \pi }\]

Answer 8

im still geting 28.25 -.-

Answer 9

ooooooooh
