The surface area of a globe in Mr. Patton's classroom is about 152.39 square inches. Find its
Snezhnost [94]

Answer:

176.89in^3

Step-by-step explanation:

when finding the volume using the surface area, the best method that comes in my mind is finding the ratio between the surface area and volume which would be r/3 for a sphere. So if given that the surface area of the sphere is 152.39 square r/3=around 1.161, and when multiplied by 152.39 is around 176.89. another similar method is deriving the radius when given its surface area which is simply taking the square root of the surface area/4pi which turns out to be 3.482357088 or 3.48 which can then be plugged into the volume formula as the radius which is (3.48^3*4pi)/3 which turns out to be the same answer!

Trigonometric functions are commonly defined as the quotient between two sides of a right triangle, associated with its angles. Trigonometric functions are functions whose values are extensions of the trigonometric reason concept in a right triangle plotted in a unit circumference (radius unit).

A company ships coffee mugs using boxes in the shape of cubes. The function g(x) = gives the side length, in inches, for a cube
Gekata [30.6K]

Answer:

The graph is attached below.

Step-by-step explanation:

The volume of the box containing the coffee mugs is,

V=x^{3}

Then the function representing the side length, in inches, for the box is:

g(x)=x

Now, it is provided that the company decides to double the volume of the box.

That is, the new volume will be:

V_{n}=2x^{3}

Then the side length, in inches, for the box will be:

g_{n}(x)=\sqrt[3]{2x^{3}} =\sqrt[3]{2}x

Then the graph representing the function, formed using the following points is:

x\ \ \ \ \ \ \ \ \ g_{n}(x)\\\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\\0\ \ \ \ \ \ \ \ \ \ \ 0\\1\ \ \ \ \ \ \ \ \ \ \ 2^{1/3}

How far in feet will a child on the edge of the merry-go-round travel? If r=6 feet, the angle is 310
goblinko [34]

Answer:

First some theory we need to solve this problem.

For a circle of radius R, the perimeter is:

P = 2*pi*R

where pi = 3.14

If we have a section of this circle, defined by an angle θ, the length of this arc will be:

A = (θ/360°)*2*pi*R

In the case of the problem, the total distance that the child travels is equal to the length of an arc of 310° in a circle of radius r = 6ft.

Using the above formula, we know that the length of this arc is:

A = (310°/360°)*2*3.14*(6ft) = 32.4 ft
