49 x 44 x 18 = 38808cm3 (cm3 means that the answer is cubed.)
To find the radius of the sphere, we need to know that the volume of the rectangular block is equal to the volume of the sphere. The volume of the rectangular block is 49 x 44 x 18 = 38,808 cm³. Equating this to the volume of a sphere (4/3πr³), we can solve for the radius which comes out to be approximately 22.18 cm.
Volume = pi*r2*h = 40715.04 cubic cm
The answer is 1,944 cm cubed
A cone with a base radius of 12 cm and a height of 18 cm has a volume of 2,714.34 cm3
The area of a parallelogram with base 18cm and perpendicular height 18cm is 324 cm2
18cm = 180mm
You can't calculate the volume here as such the height is not mentioned here and for calculating volume you need height,breadth and length.
18cm is about 7 inches
18cm = 180mm
18cm.
Let's call the sides a, b, c. The rectangular prism with the smallest surface area is a cube. If the volume is 18cm^3 (18 cubic cm), then a x b x c=18. But since it's a cube, the sides are the same size. So the formula for volume is a^3=18 (i.e. a cubed = 18) Then each side of the cube will be the cube root of 18 (which is 2.62074139 to 8 decimal places) So the dimensions of the rectangular prism rounded to 2dp are 2.62 x 2.62 x 2.62. And the surface area using the rounded values is 41.19 to 2DP
To calculate the area of a triangle, you use the formula: Area = 0.5 x base x height. Plugging in the values given, the area of the triangle would be 0.5 x 18cm x 20cm = 180 square centimeters.
