If the diameter of a circle is 86 feet, What is the radius?

43 feet

Step-by-step explanation:

The radius of a circle is half of the diameter. Since the diameter is 86 you divide that by 2 and get 43.

86 ÷ 2 = 43

d ÷ 2 = r

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

this doesn't make sense lol
