3/15=1/5=2/10 and each one is equal to 0.2, I hope this helps cx
Answer:
Radius: 10 ft
Diameter: 20 ft
Area: 314.15 ft^2
Circumference: 62.83 ft
Step-by-step explanation:
The radius can be found using the diameter. The diameter is 20 feet which is the line that is given in the circle.
The radius(r) is equal to half the diameter(d):
r = d/2 --> r = 20/2 = 10 feet
The area(A) can be found using the radius(r) and pi or 3.14
A = pi(r^2) --> A = pi(10^2) = 314.15 feet^2
The circumference(C) is found by using the radius(r) and pi or 3.14
C = 2pi(r) --> C = 2pi(10) = 62.83 feet
For #1 you know that a straight line equalys 180 degrees so the look at the 3× degrees. 180-84 =96 /3= 32 degrees . x = 32
