Answer:
31.40 ft^2
Step-by-step explanation:
You are trying to find the circumference, C = 2 * r * 3.14
1. To get the radius you divide the diameter by 2: 10 / 2 = 5
2. Plug your radius into the equation
C = 2 * 5 * 3.14
3. Your final answer should be 31.40 ft^2
Answer: 45
Step-by-step explanation: If you evaluate how much 15% of holly trees there were and the 2/5, consisting of maple trees then both of the amounts combined is, 55 then the remainder in of trees, the dogwoods, is 45
4x+8=28, therefore it’s B
Answer:
the play area is a circle with radius = 12
Step-by-step explanation:
Circle area = A= π r²
r = radius
A = 144 π = 452.39
Diameter = 2r
= 24
circumference = C = 2π r
= 24 π = 75.4
Q2)
Area = π r²
r = 15
r²= 225
area = 706.5
