Answer:
537.2 ft^2
Step-by-step explanation:
For this problem, we need to find the area of both the inner and outer circle and subtract the area of the outer circle from the area of the inner circle.
The equation for the area of a circle is:
A = πr^2
So we are given the diameters of the circles. We know that the diameter of a circle is twice the radius.
Let's find the area of the 10ft diameter circle:
A_Little = π(10/2)^2 = π(5)^2 = 25π
Let's find the area of the 28ft diameter circle:
A_Big = π(28/2)^2 = π(14)^2 = 196π
So the area of the big circle excluding the inner circle would be as follows:
196π - 25π = 171π
So 171π in terms of decimals rounded to the nearest tenth would be 537.2.
Cheers.
Answer: 34 questions
Step-by-step explanation:
If you have 40 questions, you have to find out what each question is worth which was 2.5 points per question. Then you divide 85 percent by 2.5 points and you get your answer that you got a total of <u>34 questions</u> corrects to get an 85%.
