Bruno digs them up one day and finds that he has between 30 and 50 bones he counts his bones by putting them into piles of 4 bones and finds he has 3 bones left over he counts them by putting them into piles of 7 bones and finds that he only has 1 bone left over how many bones did he have

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

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm
