What is the volume of this cone?
olchik [2.2K]

Answer:

The volume of the cone is approximately 453.0 cm³

Step-by-step explanation:

The volume of a cone is one third that of a cylinder with the same height and radius.  That gives us  1/3 πr²h, where r is radius and h is height.

However, we are not given the height of the cone, but the side length.  We can work out the height using the Pythagorean theorem, as we have a right triangle with the height, base radius, and length.  You may recall that the Pythagorean theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of it's other two sides:

a^2 = b^2 + c^2

So we can find the height of the cone with that:

10.8^2 = 7.4^2 + h^2\\h^2 = 10.8^2 - 7.4^2\\h^2 = 116.64 - 54.76\\h^2 = 61.88\\h = \sqrt{61.88}\\h \approx  7.9

Now that we have the cone's height, we can solve for its volume:

v = \frac{1}{3} \pi r^2 h\\v = \frac{1}{3} \pi \times 7.4^2  \times 7.9\\v = \frac{1}{3} \pi \times 54.76 \times 7.9\\v = \frac{1}{3} \pi \times 432.6\\v = \pi \times 144.2\\v \approx 453.0 cm^3

The amount Diego charges to detail an SUV is proportional to the time it takes him to detail the vehicle. Diego charges $37.50 t
prisoha [69]

Answer:

d = 15h

Step-by-step explanation:

Given

Charges\ \alpha\ Time

Represent charges with d and time with h

So:

d = \$37.50 when t = 2.50\ hours

Required

Determine the formula

Charges\ \alpha\ Time

In other words,

d\ \alpha\ h

Convert to an equation

d = k * h

Where

k = constant of proportion

Substitute values for Charges and Time

37.50 = k * 2.5

Solve for k

k = 37.50/2.50

k = 15

Substitute 15 for k in d = k * h

d = 15 * h

d = 15h

<em>The above formula models the situation</em>
