What is the exact volume of a cylinder with a base height of 30, and a radius of 13

Mathematics

Tcecarenko [31]4 years ago

Volume of a cylinder is \pir^{2}h. This is basically the area of a circle multiplied by the height. You can think of it as congruent circles being stacked on top of each other to create a cylinder. With the given information, all we have to do is substitute the values into the variables

V = \pir^{2}h.
V = \pi(13)^{2}x30
V = \pi x 169 x 30 = \pi 5070

Hope this helps! 
(btw if it asks for "exact" anything, leave the pi. Pi is the ratio of the circumference to its diameter, so not every circle will have a pi of 3.14.)

Choose the equation that is the standard form of
Ronch [10]
For this case we have the following equations:
 5y = 3-2x
 5y-3 = -2x
 2x + 5y = 3
 2x + 5y-3 = 0
 The standard form of the equations is given by:
 Ax + By = C
 Therefore, the equation written in its standard form is:
 2x + 5y = 3
 Where,
 A = 2
 B = 5
 C = 3
 Answer:
 
The equation that is the standard form is:
 
2x + 5y = 3

BRAINLIEST ANSWER!! The product of 3, and a number increased by seven, is -36. Translate the equation, then solve.
EleoNora [17]

Product is multiplication.

Let the number = x


3 *( X+7) = -36

Use distributive property:

3x +21 = -36

Subtract 21 from each side:

3x = -57

Divide both sides by 3:

x = -57 /3

x = -19


Check: 3 * (-19 +7) = 3 * -12 = -36


The number is -19

Anna truncated the decimal expansion of x to find the best approximation. On a number line, the location of x is between 10.9 an
podryga [215]

Answer:

Well to estimate a decimal the best option would be to round it to.

10 or 11 (For 10.9)

11 (For 11.1)

and since two of them equal 11. 

The estimation would be 11.

I hoped this helped.
