Question

The diameter of Jim’s circular flower bed is 10 feet. What is the area, in square feet, of Jim’s flower bed?

A) 10π
B) 20π
C) 25π
D) 100π
- My Guess is D, but then again, I'm not very good at Remembering the Formula for finding the Area or Circumference of a Circle.

Answer 1

The area of a circle is PiR^2
Divide 10 by 2, to get the radius.
Square the radius, 5, which gives you 25.
25Pi is your answer, which is C.)

Answer 2

Option C is correct.

Explanation:

We have been given the diameter of circular flower bed.

`Radius=(diameter)/(2)`

`Radius=(10)/(2)=5`

Area of circle is
`\pi\cdot r^2` where r is the radius of circle.

So, we will substitute values in the area of circle to calculate the value of area of circular flower bed.

`Area=\pi 5^2`

`\Rightarrow Area=25\pi`

Therefore, option C is correct.
