Question

estimate the area of the circle to the nearest unit.
A- 6,644 cm^2
B- 72 cm^2
C- 144 cm^2
D- 1,661 cm^2

Answer 1

For a circle

\[\large A = \pi r^2\]

where 'r' is the radius

Now we are given the Diameter....which is 2 times the radius...

So the radius is just that 46/2 = 23

So now we have

\[\large A = \pi (23)^2\]
\[\large A = 529\pi\]
\[\large A = 1661cm^2\]
