Can someone help me plz

Question 1:

Circumference = 3.14 x diameter

C = 3.14 x 17

C = 53.38 m

Question 2:

Circumference = 3.14 x diameter (or 2 x radius)

C = 3.14 x 6

C = 18.84 ft

Question 3:

The radius of a circle is equal to half its diameter.

10 / 2 = 5 cm

Question 4:

We want to find the perimeter of the shape as a whole. We will need a half circumference for the circular part, and 3 sides of the rectangle.

C = 1/2(3.14 x 6) = 9.42

6 + 4 + 4 = 14

Perimeter = 9.42 + 14 = 23.43 ft

Hope this helps! :)

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.
