The formula for the volume of a cone is V=PI x r^3 x h/3

The radius is given as 3 and height is 7.

V = PI x 3^2 x 7/3

V = PI x 9 x 2.333

V = PI x 21

V = 21PI cm^3

The answer is C.

Now use the distributive property to factor the expression you obtained in part D??????
Step2247 [10]

Answer:

150 + 2x

The greatest common factor of 150 and 2x is 2. Factor out a 2 from both terms:

2(75) + 2(x).

Use the Distributive Property, A(B + C) = AB + AC, to rewrite the expression:

2(75 + x).

The expression 150 + 2x is equivalent to 2(75 + x).

Step-by-step explanation:

Might want to change it up a bit bc thats the exact answer. Hope that helps

Answer:

Heun's method is also known by its other name called Modified Euler methods. This method is used in computational or mathematical science.

Step-by-step explanation:

Euler method is the method that is also pronounced in two similar stages such as Runge- Kutta methods. This method has been named after Dr. Heun.

This method is used for the solution of ordinary differential equations with its given values. There is some method to calculate this method. The improved Runge Kutta methods are also called the Butcher tableau method, the other methods are also called the Ralston methods.

Suppose a polygon has 72 sides. If the polygon is regular, what is its angle of rotation?
satela [25.4K]
The angle of rotation is the minimum angle in which you rotate a regular polygon such that the figure appears unchanged. The formula for that is dividing one angle of revolution by its number of sides.

Angle of Rotation = 360°/n
Angle of Rotation = 360°/72 = 5°
