What is the volume of a hemisphere with radius 3cm?
It is: 4/3*pi*27*0.5 = 18*pi cubic cm
What is the circumference of a circle with a diameter of 18?
If the diameter is 18, then the circumference is d*pi or 18pi. 18pi=56.52 if you use 3.14 as pi.
A square is inscribed in a circle of area 18 PI find a side of a square?
Area of circle: 18pi Radius of circle: square root of 18 = 3 times square root of 2 Using Pythagoras' theorem each side of the square is 6 units in length
What is the volume of a cube with a side length of 6 meters and a hemisphere with diameter of 6 meters?
Cube: 216 m^3 Volume of cube=s^3 s=6 6^3=216 Hemisphere: 18pi m^3 ~ 56.5486678 m^3 sphere: (4/3)pi(r^3) hemisphere: ((4/3)pi(r^3))/2=(4/6)pi(r^2)=(2/3)pi(r^3) d=6 r=3 (2/3)pi(3^3)=(2/3)pi(27)=(54/3)pi=18pi
If the lateral areas of two similar cylinders are 50pi cm sq and 18pi cm sq and the volume of the smaller cylinder is 54pi cm cubed what is the volume of the larger cylinder?
The two cylinders are similar - they are of corresponding shapes but one is x times bigger than the other. If a cylinder is x times bigger in a single dimension, it will be x2 times greater in measurements involving two dimensions (i.e. area) and x3 times bigger in three dimensions (volume). Here, the ratio in two dimensions is 50pi / 18pi. This cancels to 25/9. So in terms of area, one is 25/9 times larger. x2 = 25/9 So x = sqrt25/sqrt9 = 5/3 and x3 = 53/33 = 125/27 (If you prefer, one can just write (25/9)3/2 = 125/27) In terms of volume, then, the big cylinder is 125/27 times bigger. Multiply this ratio by the volume of the small cylinder... 54pi x 125/27 cancels to 2pi x 125 = 250pi cm3. ...and you have the volume of the big cylinder. (It's tidiest to leave the answer in terms of pi.) This is just a question about scale factors, and the identity of the objects as cylinders is irrelevant, because they are similar. The way in which the figures neatly cancel without producing any horrendous decimals suggests that this question came from a textbook or an exam paper.
The cylindrical can has a length of 18.00cm and diameter of 2.00cm what is the volume?
The volume of a cylinder is volume=((Pi)*radius^2)*height. Therefore it is equal to 1^2*pi=pi times height(18) =18pi cm cubed
What is the volume of a hemisphere with radius 3cm?
It is: 4/3*pi*27*0.5 = 18*pi cubic cm
A circle has a circumference of 18 pi so what is the radius of this circle?
If a circle has a circumference of 18pi, the radius is 9.
How do you find the volume of a cylinder w a height of 8in and a diameter of 3?
volume of a cylinder = pi r2 h so volume of w = pi x 1.52 x 8 =18pi =56.5
A circle has a curcumference that measures 18pi inches. What is the radius in inches of the circle?
Circumference equals 2 X pi X radius, so work backwards. 18pi=2 X pi X radius divide pi. 18= 2 X radius divide by 2. radius= 9.
What is the measure of the central angle if the arc length is 36 and the radius is 9?
It is: 36/18pi times 360 = about 229 degrees
If you have a cake recipe that is 6 inches in diameter and 2 inches high but you pour the batter into a round cake pan that is 8 inches in diameter how tall will the cake be?
The volume of the batter is the same. Volume in the 6 in pan: Pi r2 h = 18Pi . Volume in the 8 in pan: 16hPi . Equating the two: 18Pi = 16hPi gives h = 9/8 in.
What is the circumference of a circle whose radius is 9cm?
C=2*pi*r C=2*pi*9 C=18pi C=18*3.141592=56.548656...
The circumference of a circle is 18pi inches Determine the area of the circle?
First we have to find the radius: 2*pi*radius = 18*pi Divide both sides by 2*pi to find the radius: radius = 9 inches Area of a circle = pi*radius2 Area = pi*92 = 81pi or 254.4690049 square inches
What is the circumference of a circle with a diameter of 18?
If the diameter is 18, then the circumference is d*pi or 18pi. 18pi=56.52 if you use 3.14 as pi.
What is the circumference of a circle if its area is 81π?
18pi
You have a filled glass 8 inches tall with a radius of 1.5 inches If you pour the water into a 12 inch glass with a radius of 2.5 inches How much more water can that glass hold?
It can hold about 179.07 cubic inches more of water. Volume = pi r^2 The volume of the water in the 8 inch glass = 8 pi (1.5)(1.5) = 18pi = about 56.55 cubic inches The volume of the 12 inch glass = 12 pi (2.5)(2.5) = 75 pi = about 235.62 cubic inches The difference in volume is 57 pi or about 179.07 cubic inches *previous answer used a different size glass
