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
The diameter is always double the radius so in this case, it is 18cm
r= 9 so diameter is 2x the radius =18 cm
The area is 254.47 in2
9 cm (r = d/2)
A circle with a radius of 9 cm has an area of 254.47 square cm
radius = 18/2 = 9 cm
A circle with a radius of 9 feet has an area of 254.47 square feet.
648pi. (pi = 3.14159...)Area of a circle = (pi) x (radius squared)= (pi)(9 squared) = (pi)81.Area of a cylinder = area of circle x height.= (pi)81 x 8= 648(pi)
I assume you want the area of the sector with angle 120o and radius 9 cm: 120o is 120/360 = 1/3 of a full circle. ⇒ area of sector is 1/3 area of full circle ⇒ area_of_sector = 1/3 x π x radius2 = 1/3 x π x (9 cm)2 = 27π cm2 ≈ 84.82 cm2
Using 3.14 as Pi the area of circle is: 0
A circle with a radius of 4.5 cm has a circumference of 28.27 cm
The area of a circle is pi times radius times radius. 6 cm = 2 times 3 cm radius = 3 cm. SO, pi times 3 cm times 3 cm 9 pi pi is approximately 3.141592... 9 times 3.141592... is 28.274328...
If you triple the radius of a circle, the area will increase by 9. Area is proportional to the square of the radius.
The area of a circle with a radius of nine centimeters is: 254.5 cm2

The area of a circle is figured out using the formula Now, the circle we are given has a radius of 9cm. So, the area of the circle would be: Area = 3.14 x (9)2 = 3.14 x 81 = 254.34 cm2 The area of the circle in question is 254.34 cm2
