Why say fifteen points when it's only 5; people can see how much it's worth before even doing it.

Anyways, is there a plus in between the 2f 3 and between the -14 3?

If so, then w and k equal all real numbers and
f =   \frac{ - 1005}{22}  +  \frac{12}{11}k +  \frac{1}{11} {w}^{2} k  -  \frac{ 81}{22}  {w}^{2}
However if not, then I suggest downloading photo math and inserting it in the calculator itself to be exact.

How do you find volume of sphere, cylinder, cone ? ... explaining please
boyakko [2]

Answer:

hmmmm

Step-by-step explanation:

Cone

The volume of a cone is linked to the volume of a cylinder. A cone is one third of the volume of a cylinder. The volume of a cone is ¹/₃ × π × r² × l. To calculate the volume we multiply these values together. The answer will be written in units³.

Sphere

The volume of a sphere is ⁴/₃ × π × r³. To calculate the volume we multiply these values together. The answer will be written in units³.

Cylinder

The volume of a cylinder is π × r² × l (r is the radius of the circle and l is the length of the cylinder). To calculate the volume we multiply these values together. The answer will be written in units³. It is more accurate to use π = 3.142 or the π button on a calculator.

   A cone is a 3D shape with 2 faces and one edge

   A sphere is a 3D shape. It has one continuous face and no edges

   A cylinder is a type of prism. It has 3 faces and 2 edges

Please help i keep getting the wrong answers
Mrrafil [7]

Answer:

10 inches

Step-by-step explanation:

Surface Area = π R² + π R L [ L is Slant Height ]

200 π = π (10)² + π (10) L

200 π = π (100) + π (10) L

200 π - 100 π = 10 π L

100 π = 10 π L

100 π / 10 π = L

10 = L

L = 10 inches

Hope this Helps......
