second box= feet or square feet

2.) 31.41 feet 1.)

Step-by-step explanation:

1.) Divide the diameter in half, to get the radius.

10 / 2 = 5

2.) Use the circumference of a circle equation, 2r.

2(5) ≈ 31.41 feet

3.) Remember that circumference is not in square feet, as it is the length of the perimeter of the circle, not an area.

4.) To get the exact circumference, convert 31.41 to radians.

31.41( / 180) = 0.548207918

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
