Answer:
Area = 25.12 square units.
Perimeter = 20.56 units
Step-by-step explanation:
If you are looking for area, here goes:
Area of circle = π * r^2
Area of semi-circle = S = (1/2) *π * r^2
S = (1/2)*π*(4^2) = (1/2)π*16 = 8π square units = 25.12 square units
Or if you are looking for the perimeter:
Circumference C = 2*π*r
Half-circumference = (1/2)C = (1/2)*2*π*r = π*r = π*4
Perimeter of semi-circle = 4 + 4 + 4π = 8 + 4π
From the looks of the graph, it looks like when the line is on 2, it’s 0 (I hope this helps)
Answer: 85.13
Step-by-step explanation:
We know:
Circumference = 2*3.14r
Area of a circle = 3.14r²
We need to find the radius given the circumference before solving for the area:
32.7 = 2*3.14r
32.7/6.28 = 6.28r/6.28
r = 5.20700637
Now that we know the radius, we can plug it in to find the area:
A = 3.14(5.20700637)²
A = 3.14(27.1129153)
A = 85.134554
The answer is D because 3 can’t go to different numbers on the x column
