A cone has a volume of 2,355 cubic inches and a height of 10 inches. How many inches is the diameter of the cone

Hello there,

Okay well first we right down what we already know:

 - volume of 2,355 cubic inches

 - the height is 10 inches

Now we write down the equation for the volume of a cone: V = πr²

                                     2,355 = πr²

                          2,355 / 10/3 = 706.5 = πr²

                           706.5/π = r²= 224.89

                            r = 15 inches

                           diameter = 30 inches

Hope I helped,

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
