A food company distributes its tomato soup in two cans of different sizes. For the larger can, both the diameter and the height

Lady_Fox [76]

Problem

A food company distributes its tomato soup in two cans of different sizes. For the larger can, both the diameter and the height have been increased by 15%.

By what percentage does the volume increase from the smaller can to the larger can? Round your answer to the nearest percent.

Solution

the volume of a cylinder is given by:

$V=\pi r^2h$

We know that the diameter=radius and the height are increased by 15% so then the new volume can be calculated on this way:

$V=\pi(1.15r)^2\cdot(1.15h)=1.15^2\cdot1.15\cdot\pi\cdot r^2\cdot h=1.52\pi r^2h$

And the new volume would increase about 52%

ANSWER THREE THROUGH FIVE , ILL GIVE YOU BRAINLIST!!!

Ray Of Light [21]

Answer:

Step-by-step explanation:

3) diameter of penny = 19 mm

r = 19/2 = 9.5 mm

Area of penny = πr²

= 3.14 * 9.5 * 9.5

= 283.385

= 283.39 mm²

Diameter of nickel = 21 mm

r = 21/2 = 10.5 mm

Area of nickel = πr²

= 3.14 * 10.5 *10.5

= 346.185

= 346.19 mm²

346.19 - 283.39 = 62.8 mm²

Area of Canadian nickel is greater than Canadian penny by 32.6 mm²

4) r = 12 mm

Area of circle = πr²

= 3.14 * 12 * 12

= 452.16 mm²

5) r = 20 cm

Area of circle = πr²

= 3.14 * 20 * 20

= 1256 cm²

Find the product (8/6n-4)(9n^2-4)

Leokris [45]

Answer:

4(3n+2) or 12n+8

Step-by-step explanation:

Given expression is:

$(\frac{8}{6n-4})(9n^{2}-4)$

The numerator of the fraction will be multiplied with 9n^2- 4

So, Multiplication will give us:

$=\frac{8(9n^2-4)}{6n-4}$

We can simplify the expression before multiplication.

The numerator will be broken down using the formula:

$a^2 - b^2 = (a+b)(a-b)\\So,\\= \frac{8[(3n)^2 - (2)^2]}{6n-4}\\ = \frac{8(3n-2)(3n+2)}{6n-4}$

We can take 2 as common factor from denominator

$=\frac{8(3n-2)(3n+2)}{2(3n-2)}\\After\ cutting\\= 4(3n+2)$

Hence the product is 4(3n+2) or 12n+8 ..
