Answer:
1) 37.7 ft 2)75.4
Step-by-step explanation:
the formula for circumference= 2 x radius x pi
so i halved the first one as its the diameter but for the second one they already gave the radius
hope this helps!
First, find the value of x. Note that the angles x, 0.5x and 3x sum up to 4.5x, and that this sum has the value 180 degrees. Solving this equation for x, we get x = 40 degrees.
Now, 0.5x and 0.5y are vertical angles, and thus x = y. So, with x being 40 degrees, y = 40 degrees.
Red Circle:
First find the diameter
We can do that by counting the squares
Diameter:4
The radius is half of the diameter
4/2=2
Radius of the Red Circles:2
Blue Circle:
Diameter: 2
2/2=1
Radius of the Blue Circle:1
