Answer:
8.46
Step-by-step explanation:
Hey is 4 to get a good job of you getting your in the time you can join your in the time you can join
The area of the circle = π r² = π (d/2)²
Where r is the radius of the circle
And d is the diameter of the circle
d = 2r OR r = d/2
given d = 10 in ∴ r = d/2 = 10/2 = 5 in
∴ The area of the circle = π r² = π * 5² = 25π ≈ 78.54 in²
The correct answer is the fourth option 78.54
==========================================
very important note:
There is a mistake in the dimension of the answers.
The dimension of the given diameter is inch , while the dimensions of the answers is square cm.
If it is required to find the area in square cm
∵ 1 inch = 2.54 cm
∴ r = d/2 = 10/2 = 5 in = 5 * 2.54 cm = 12.7 cm
∴ Area = π r² = π * (12.7)² = 161.29π ≈ 506.7 square cm
Answer: 39
Step-by-step explanation:
SInce the problem asks for the expression when a=2 and d=5, you olug in the values of a and d and solve.
(5)²+3(2)+6+(2) [exponent]
25+3(2)+6+2 [multiply]
25+6+6+2 [add]
39
After plugging in a=2 and d=5, we got 39 as our answer.
