Jude estimates that his index finger is 3 inches long. He calculates the circumference of one of his bongo drums to be 27 inches. Suppose Jude used his finger as a referent to measure the circumference of the drum. How many finger lengths along the circumference of the drum would he have counted?

9 finger lengths

Step-by-step explanation: Since the circumference is the middle line passing through (usually a circle) 27/3 equals 9, which basically means that 9 of Jude's index fingers can pass through the circumference of one of his bongo drums. Hope this helps, 15402256.

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
