The volume of a right circular cone is 300 cubic inches. What is the volume, in cubic inches, of a right cylinder th
AlexFokin [52]

Answer:

The volume of the cylinder is 900 cubic inches

<em />

Step-by-step explanation:

Given

Let V1 represent the volume of a cone and V2 represents the volume of a cylinder

V_1 = 300in^3

Required

Determine the volume of a cylinder with same dimension

The volume of a cone is calculated as:

V_1 = \frac{1}{3}\pi r^2h

The volume of a cylinder is calculated as:

V_2 = \pi r^2h

Since, the cone and cylinder have the same dimensions, we can substitute \pi r^2h for V_2 in V_1 = \frac{1}{3}\pi r^2h

So, we have:

V_1 = \frac{1}{3} * V_2

Multiply both sides by 3

3 * V_1 = \frac{1}{3} * V_2 * 3

3 * V_1 = V_2

V_2 = 3 * V_1

Substitute 300in^3 for V_1

V_2 = 3 * 300in^3

V_2 = 900in^3

<em>Hence, the volume of the cylinder is 900 cubic inches</em>

Which ordered pair is identified by the letter "G" on this coordinate grid?
Natasha2012 [34]
Hey there!

When we say coordinate pair, we usually express our pair in the form of:

(x, y)

This means the point on the x axis is first, and the point on the y is second in the parenthetical format of coordinates. We know that the x coordinate is the horizontal one, while the y is vertical.

If we start with the x axis, we see that our point, G, is just below the number 2. That means our x coordinate is 2. For the y coordinate, we see that the point is directly lined up with the -3, therefore our y coordinate is -3.

Therefore, our coordinates are (2, -3).

Hope this helps!

The piecewise function all the way to the left (x + 3) should have an ending point shaded in. [At x = -2] The next function ((x^2) -1) should have both ending points left unshaded. Finally, the logarithm function should have a shaded in starting point [At x = 1] and should have an unshaded ending point at x = 3.

Wewaii [24]

A company makes baseball cards in packs of 10, boxes of 100, and cases of 1,000. A store orders a total of 15,470 cards. How can the company fill the order in the exact amount?

Answer: The company can fill the order in exact numbers as:

15 cases, 4 boxes, 7 packs

15 cases contain 15 \times 1000=15000 cards

4 boxes contain 4 \times 100 =400 cards

7 packs contain 7 \times 10 = 70 cards

Therefore, the total cards are:

15000 + 400 + 70 = 15,470

the attendance of your club increased by 30% from last year. there are 195 people in the club now. a. write a proportion to find
astra-53 [7]

Answer:

A.

\dfrac{x}{195}=\dfrac{100}{130}

B. 150

Step-by-step explanation:

Let x be the number of people at the club last year.

The attendance of your club increased by 30% from last year. This means that if the last year attendance was 100%, this year attandance is 100% + 30% = 130%

Thus,

x people - 100%

195 people - 130%

A. Write a proportion:

\dfrac{x}{195}=\dfrac{100}{130}

B. Cross multiply:

130\cdot x=100\cdot 195\\ \\130x=19,500\\ \\13x=1,950\\ \\x=\dfrac{1,950}{13}=150
