Using TT =3.14 what is the circumference of a circle with a diameter of 7 units round your answer to the nearest hundredth

 21.98 units

Step-by-step explanation: the formula for circumference of a circle is 2 x pi x r(radius) or pi x d(diameter). pi(3.14) x 7 = 21.98

add an !

step-by-step explanation:

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
