A multiple-choice test contains 11 questions. There are four possible answers for each question. In how many ways can a student answer the questions on the test if the student can leave answers blank

Step-by-step explanation:

Given

Required

Determine the number of ways

If the student can leave answers blank, the the options become:

The student can pick any of the 5 available options in each of the 11 questions.

Hence:

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
