Answer:

Option (c) is correct.

The surface area of a solid figure is the sum of the areas of its exterior surfaces.

Step-by-step explanation:

Given : the surface area of a solid figure

We have to choose which out of given options best describes the surface area of a solid figure.

Since, the surface area of a solid figure is the area of its outer surfaces that is the sum of the areas of its exterior surfaces.

We can find the surface area of three dimensional figures using two dimensional view that is from the top view, the side view and the front view.

So, the surface area of a solid figure is the sum of the areas of its exterior surfaces.

Which explanation correctly tells whether these ratios are equivalent and why?

Reptile [31]

<h3><u>Answer:</u></h3>

<u>Option A (Yes because 3 x 2 = 6 and 14 x 2 = 28.) is correct.</u>

<h3><u>Step-by-step explanation:</u></h3>

<u>This is because if we simplify 3/6 and 14/28, both of them will get 1/2. This means that only A and C are possible.</u>

=> Option A is correct because 3 x 2 does equal 6 and 14 x 2 does equal 28.
=> Option C is incorrect because 3 x 5 does not equal 14 and 6 x 5 does not equal 28.

The value of the expression

r-ruslan [8.4K]

Answer:

f(5) = 75

Step-by-step explanation:

The function is f(x) = 2x^2 + x(100 - 15x).

Evaluate this function at x = 5: replace each instance of x with 5:

f(5) = 2(5)^2 + 5(100 - 15·5)

Order of operations rules require evaluating the expression enclosed in parentheses first. We get:

f(5) = 2(5)^2 + 5(100 - 15·5)

= 50 + (100 - 75), so that:

f(5) = 50 + 25 = 75

f(5) = 75

Surface area of cylinder

steposvetlana [31]

Answer:

The answer is C. $256\pi$ $in^2$ .

Step-by-step explanation:

To solve for the surface area of this cylinder, start by using the cylinder surface area formula, which is $SA=2\pi rh+2\pi r^{2}$ . Next, plug in the information given from the problem into the formula, which will look like $SA=(2)(\pi )(8in)(8in)+(2)(\pi )(8in^{2})$ . Then, simplify the equation, which will look like $SA=(128in)(\pi) +(128in)(\pi)$ . The next step is to simplify the equation further, which will look like $SA= 256\pi$ $in^{2}$ . The final answer is $256 \pi$ $in^2$ .

A photograph of a full moon is enlarged so that the diameter appears 2 times larger. How much larger

statuscvo [17]

Answer:

ans 3

Step-by-step explanation:

Circumference is distance round a figure. When diameter is trippled, the circumference will also tripple.

Here is a proof

Take the moon to have circular shape and has diameter d

Circumference is given by C=πd

When the new diameter is trippled, diameter will be 3d and the new circumference will be

C=π3d=3πd

Evidently, the new circumference is three times the original circumference. Therefore, for this case, the new circumference will be 3 times the original
