I assume you are talking about a circle, and want the area. Dividing the diameter by 2 will give you the radius. Next, use the following formula:
A = pi x r2
(Area = pi x radius squared, where pi is about 3.14)
A cylinder with a height of 10 inches and a diameter of 8 inches has a surface area of 351.86 square inches.
To convert dimensions from inches to square feet, first calculate the area in square inches by multiplying the length and width: 10 inches × 12 inches = 120 square inches. Then, convert square inches to square feet by dividing by 144 (since there are 144 square inches in a square foot): 120 square inches ÷ 144 = 0.8333 square feet. Thus, 10 inches by 12 inches is approximately 0.83 square feet.
SA = ~314.159 square inches.
The area is 78.5 square inches.
No. A diameter is a length, which may be measured in feet. Square feet are used to measure areas. You cannot convert directly from linear measures to square measures.
The area of the sector of a circle which has a diameter of 10 inches if the length of the arc is 10 inches is: 25 square inches.
It is: 25*pi square inches
The largest square that could fit in a circle of diameter 10 inches has dimensions 5sqrt(2) inches by 5sqrt(2) inches.
A cylinder with a height of 10 inches and a diameter of 8 inches has a surface area of 351.86 square inches.
Formula: square inches x 6.4516 = square centimeters
To convert dimensions from inches to square feet, first calculate the area in square inches by multiplying the length and width: 10 inches × 12 inches = 120 square inches. Then, convert square inches to square feet by dividing by 144 (since there are 144 square inches in a square foot): 120 square inches ÷ 144 = 0.8333 square feet. Thus, 10 inches by 12 inches is approximately 0.83 square feet.
radius = square root of (78.5/pi) = 4.998732446 diameter = 2*4.998732446 = 9.997464892 or about 10 inches
SA = ~314.159 square inches.
The area is 78.5 square inches.
No. A diameter is a length, which may be measured in feet. Square feet are used to measure areas. You cannot convert directly from linear measures to square measures.
V = volume of a cylinder = Pi*Diameter*depth 144 square inches = 1 square foot volume of each hole: Pi*10*4 ~= 125.7 square inches / 144 square inches/square foot = 0.8727 square feet We have 30 such holes so total volume = 30*0.8727 = 26.18 square feet.
V = volume of a cylinder = Pi*Diameter*depth 144 square inches = 1 square foot volume of each hole: Pi*10*5 ~= 157.1 square inches / 144 square inches/square foot = 1.091 square feet We have 30 such holes so total volume = 30*1.091 = 32.73 square feet.
