What is the area of a parallelogram with base 9 and height 5?

Accepted Answer

45

Answer

Area = base × height = 9 × 5 = 45.

Question 2

What is the volume of a cone with radius 3 and height 4? (use π ≈ 3.14)

Accepted Answer

37.68

Answer

Volume = ⅓πr²h = ⅓(3.14)(9)(4) = 37.68.

Question 3

What is the area of a circle with diameter 10? (use π ≈ 3.14)

Accepted Answer

78.5

Answer

Radius is 5, so area = πr² = 3.14(25) = 78.5.

Question 4

What is the perimeter of a rectangle with length 12 and width 7?

Accepted Answer

38

Answer

Perimeter = 2(l + w) = 2(12 + 7) = 38.

Question 5

What is the sum of the interior angles of a pentagon?
