Answer:
3.14 square units
Step-by-step explanation:
Circumference of a circle = 2πr
2πr = 6.28
r = 6.28/2π
r = 3.142/π
Area of a circle = πr^2
slot in the value of r
Area of the circle = π( 3.142/π)^2
" = π(9.87/ π^2)
" = 9.87/π
π = 3.14
Area of a circle = 9.867/ (3.14)
" = 3.14 square units
Children = .65 * people

C. Euclid is known as the father of Geometry
Answer:
Angle ABC = 58
_________________
These two angles are opposite but meet at the same vertex. This means that they are equal to each other. To solve the equation below, isolate the variable and you have your answer!
3x - 14 = 2x + 10
-2x -2x
x - 14 = 10
+14 +14
x = 24
Angle ABC
3(24) - 14 = ?
72 - 14 = 58
