What is the volume of a cone that has a height of 10 feet and a base with a diameter of 2 and half feet?

1 answer:

6 0

Volume of a cone: 1/3 $\pi$ r²h
r is the radius (diameter ÷ 2) and h is the height.

Find the radius first using the diameter: 2 $\frac{1} {2}$ ÷ 2 = 1.25

Now plug in the numbers into the formula.

1/3 $\pi$ 1.25²10 = <span>16.4

The volume of the cone is 16.4 cubic feet.

Create and solve an appropriate equation: Maria's earnings = Liam's earnings

0.20x = $625+0.10x.

Find x.

0.10x = $625; thus, x = $6250. At this level of food sales, these two people earn the same amount.

Fill in the blanks. If a function is one-to-one then its inverse will be _____________. If a function is NOT one-to-one then its

katrin [286]

Answer:

Inverse functions Inverse Functions If f is a one-to-one function with domain A and range B, we can de ne an inverse function f 1 (with domain B ) by the rule f 1(y) = x if and only if f(x) = y: This is a sound de nition of a function, precisely because each value of y in the domain of f 1 has exactly one x in A associated to it by the rule y = f(x).
