Question

What is the area of the circle in terms of pi? 3.7 m is the diameter

Answer 1

Area of a circle is :
$\pi {r}^{2}$
Where r is the radius.
To find r, you divide the diameter by 2
$\frac{3.7}{2} = 1.85$
Then,
$\pi {1.85}^{2} \\ = \frac{1369}{400} \pi \\ or \\ = 3.4225\pi$

Answer 2

The formula for the area of a circle is Area= pi(radius)^2 


so that would mean half of 3.7 is the radius which is 1.85. 1.85^2 is 3.42 


3.42π is your answer
