If the radius of a circle is 8 inches what is the area?
Area of a circle = pi x r(squared) Area = 2.1415927 x 8 (squared) Area = 2.1415927 x 64 Area = 137.06 inches
What is the width of a rectangle with the length of 8 inches greater than its width find the width of the rectangle if its area is 108 square inches?
Let the width be x inches. So, the length will be 'x+8' inches. Area will be (x)*(x+8) sq. inches. This implies , (x)*(x+8) = 108 x2 + 8x - 108 = 0 Solve for x and you get the width.
What is an 8 INCHES by 13 INCHES paper?
An 8 x 13 inch paper has a surface area of 104 square inches.
Find the area of a parallelogram if the base is 8 inches and the height is 3 inches?
8 x 3 = 24 square inches
How many square inches in a 4 by 8 cylinder?
4 . 8 =32 A cylinder is round and its circular area is dependant on one dimension only - its diameter or radius. If the diameter is 4 inches then the area is Pi/4 x 42 = 4*Pi If the diameter is 8 inches then the area is Pi/4 x 82 = 16*Pi If you needed the surface area and the diameter was 4 inches and the height was 8 inches, then the surface area would be (circumference) x height = (Pi x 4) x 8 = 32*Pi square inches. Of course Pi = 3.14159 to the nearest 5th decimal.
