The volume of a cone is calculated through the equation,

V = (πD²/4)(H)/3

where V is volume,
D is diameter
H is height

Substituting the known values,

V = (π(3m)²/4)(4m)/3

Simplifying,
V = 3π m³

The volume of the cone is equal to 3π or 9.42 m³. The value should complete the volume statement of the cone.

A gym memebership costs a flat fee of $68 and an additional $19.99 per month.Since she became a member Ellen has paid the gym $2

fomenos

Answer:

She has been a member of the gym for seven months

Step-by-step explanation:

In this question, we are asked to calculate the number of months a customer has been a member of a gym, given the pricing template of the gym.

Now, as we can see from the question, there are two kinds of fees to be paid. The flat fee and the subscript class.

First, let’s represent the number of months she has been a member of the gym by m. This means the total amount of money she has paid for m months would be m * 19.99m

Now, recall, we have a flat fee of $68, adding this to the total monthly payment for m months bring the wages to 19.99m + 68

This is said to equal $207.93

This means;

19.99m + 68 = 207.93

19.99m = 207.93 -68

19.99m = 139.93

m = 139.93/19.99 = 7

During a 90-day monsoon season, daily rainfall can be modeled by sinusoidal functions. A low of 4 inches of rainfall was recorde

Phoenix [80]

Answer:

$25.4\,days \leq t \leq 34.6\,days$

Step-by-step explanation:

Let consider the following model:

$c(t) = A \cdot \sin \left(\frac{2\pi \cdot t}{T} \right) + \bar c$

The average is given by the following formula:

$\bar c = \frac{c_{min}+c_{max}}{2}$

The maximum value is:

$c_{max} = 2 \cdot \bar c - c_{min}$

$c_{max} = 2\cdot (8\,in) - 4\,in$

$c_{max} = 12\,in$

Amplitude is:

$A = 12\,in - 8\,in$

$A = 4\,in$

The sine function has a periodicity of $2\pi$ , where is minimum is reached at $\theta = \frac{3\pi}{2}$ , when t = 30. The period of the cycle is:

$T = \frac{2\pi}{\frac{3}{2}\pi }\cdot (30)$

$T = 40$

The complete expression is:

$c(t) = 8\,in + 4\,in \cdot \sin \left(\frac{2\pi}{40}\cdot t \right)$

The times associated with $c = 5\,in$ are, respectively:

$8\,in + 4\,in \cdot \sin \left(\frac{2\pi}{40}\cdot t \right) = 5\,in$

$4\,in \cdot \sin \left(\frac{2\pi}{40}\cdot t \right) = -3\,in$

$\sin \left(\frac{2\pi}{40}\cdot t \right) = -0.75$

$t = \frac{40}{2\pi}\cdot \sin^{-1} (-0.75)$

Instants are, respectively:

$t_{1} \approx 25.4\,days$

$t_{2} \approx 34.6\,days$

Period is:

$25.4\,days \leq t \leq 34.6\,days$
