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.

_____ ft2

Answers

Answer 1
area = 3.14(r)^2
3.14(3.5)^2
=38.465
=38.5 (rounded)
Answer 2

Answer:

Pretty sure it's 38 ft^2

Step-by-step explanation:

Formula for circles=πr^2

So radius is 3.5 because radius is half the diameter

so 3.5^2=12.25

And 12.25 times 3.14 is your answer

Since theres 4 numbers and 60 spins if you divide it you get the average number that all the numbers would land on. 2 would be landed on 15 times if it went exactly to the calculations. not 100% sure though

The aim of the study is to test whether smoking is associated with higher risk of gingivitis. The study found that in 40 pairs the low-exposed twin had gingivitis while the high-exposed twin did not, in 23 pairs the high-exposed twin had gingivitis while the low-exposed twin did not, while in the remaining 101 pairs the twins had same status: in 15 pairs both had gingivitis and in 86 pairs both did not have gingivitis.a.
