2. Multiply the Circumference by the Height of the column. 15.708 x 25 = 392.7 SF
3. Multiply the SF by \$1.25  392.7 x 1.25 = 490.88
4. Multiply the cost to paint one column by 10 (How many Columns) \$490.88 x 10 = \$4908.80

Example:

A painter charges by the square foot and needs to determine the Area of a Column that is 25' tall and 5' in diameter. He will charge \$1.25 per square foot.

There are 10 columns total. Example:

Calculate the Linear Feet around a circle that has a 12' diameter.

12 x 3.1416 = 37.6992' Example:

Calculate Cubic Feet (Volume) in a cone with 5' radius that is 14' tall

1.0472 x 5 x 5 x 14 = 366.52

Example:

Calculate Cubic Feet (Volume) in a pyramid with dimensions of 10' x 10' with 14' height.

10 x 10 x 14 = 1400

1400 ÷ 3 = 366.52

Example:

Calculate Cubic Feet (Volume) in a tank that is 20' Tall with an 8' Diameter.

.7854 x 8 x 8 x 20 = 1005.312 NOTE: To convert to square yards, divide by 9. For Cubic yards divide by 27. USE THIS MENU TO LOCATE MORE TIPS FOR EVERYDAY MATH
