Pi x 9^2 or 81pi. Pi r^2 also the formula for computing the area of a circle.
A cylinder with a radius of 5 centimeters and height of 9 centimeters
The curved surface area is 113.1 units2
A mug in the shape of a cylinder has base with a radius of 4 cm How many milliliters of liquid does it hold if filled to height of 9 cm? Volume of a cylinder = area of base * height Base is a circle Area of a circle = π * radius squared The radius = 4 cm Area = 3.14 * r * r = ____ square cm Area = 3.14 * ___ * ___ = ____ square cm Volume of a cylinder = area of base * height You know area of the base and the height = 9 cm. Volume of a cylinder = ______ * _____ = _____ cubic cm 1 cubic cm = 1 milliliter 150 cubic cm = 150 milliliter Answer ≈ 450-455 ml
A cylinder with a base radius of 4 units and a height of 9 units has a volume of 452.39 units3
Area = pir2+2pirh=3.1416x42+2X3.1416x4x9=50+226=276
The volume of a cylinder is the area of its base multiplied by the height. [In this case, the "height" of the cylinder is the depth of the pool.] The base of the pool is a circle with radius of 9 m. The area of a circle is the radius squared times pi, which in this case is 81*pi m^2. Multiply this by the depth of 3.5 and you get 283.5 * pi cubic meters.

The surface area of cylinder with radius equal to 4 and height equal to 9 is 326.725 square units.
The answer is 226.19 units2The formula is AL = 2*Pi*radius*height
Approximately 367.57 units2
First you do the area for the base which is a=3.14r2. So 9 units is the diameter. 4.5 is the radius. The answer for the base is 63.6. So volume equals base x height. You do 63.6 x 2.5 and the answer is 159.
SA = about 622.03 units2
