Question

Claire has a hot tub with a diameter of 7 feet. She wants to purchase a cover to protect the hot tub. What is the area of the cover? Use Pi = 3. 14 and round the answer to the nearest square foot.

Answer 1

38 square feet

Explanation:

How do we find the area of a circle?

❖ The area of a circle is πr², where r = radius. For this case, we're going

to approximate pi as 3.14.

How do we find the radius given diameter?

❖ We are given the diameter of Claire's hot tub as 7 feet. The diameter

is 2x the radius, so we divide 7 by 2 to get the radius, which is 3.5

feet.

Solving

• 
  `3.14*3.5^2`
• 
  `3.14 *12.25`
• 
  `38.465`
• 38.465 ≈ 38

Therefore, the answer is 38 square feet. Have a lovely rest of your day/night, and good luck with your assignments! ♡
