Question

The diameter of a circle is 5 ft. What is the area of the circle? Use 3.14 for Pi.

Answer 1

\[area = \pi r^2\]
and
\[r = diameter/ 2\]

so first, find r by dividing the diameter by 2, then find the area by squaring r and multiplying by pi.

Answer 2

\[A = \frac{ \pi d ^{2} }{ 4 }\]
A=Area
d=diameter

Answer 3

19.6?

Answer 4

yh

Answer 5

Thank you :)

Answer 6

Area of a circle is \[\pi r^2\].... And Radius is half of diameter...
r=d/2
So, area= \[\pi d^2/4\]
