The art teacher started class with a block of clay that weighed 79 1/10 pounds. The students used 65 9/10
pounds of the clay during 100 class.
How much clay was not used by the students?

A 13 pounds
B 14 pounds
C 14 100 pounds
D 1419 pounds

The closest answer would be A. 13 pounds bc 79.1-65.9=13.2

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
