Question

Determine the area of a circle with radius 5 feet. Question 1 options: A. 25 ft2 B. 25πft2 C. 10πft2 D. 5πft2

Answer 1

Answer:

25π ft²

Step-by-step 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 2

Answer:

$25\pi \: {ft}^{2}$

Option B is the right option.

Solution,

Radius(r)=5 feet

Area of circle=?

Now,

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

Hope this helps..

Good luck on your assignment..
