Answer:

25π ft²

Explanation:

→ Utilise area of a circle formula

π × r²

→ Find the radius

r = 5 (stated in the question)

→ Substitute this value into the area of a circle formula

π × 5²

→ Simplify

25π

→ Since the radius was in feet, the units would be ft² because we are calculating area

25π ft²

Answer:


25\pi \: {ft}^(2)

Option B is the right option.

Solution,

Radius(r)=5 feet

Area of circle=?

Now,


area = \pi {r}^(2) \\ \: \: \: \: \: = \pi * {(5)}^(2) \\ \: \: \: \: = \pi * 25 \\ \: \: \: \: = 25\pi \: {ft}^(2)

Hope this helps..

Good luck on your assignment..
