What is the area of the shaded region? (Approximate π to be 3.14)

  about 113.04 square inches

Step-by-step explanation:

No angles are indicated, so we must assume the sector is 1/4 of the circle. Then its area is 1/4 of that of a circle with radius 12 in:

  Circle area = πr²

  Sector area = (1/4)π(12 in)² = 36π in²

  Sector area ≈ 36(3.14) in² = 113.04 in²

it could be 1,3 and more others to create a cylinder.

step-by-step explanation:

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
