Answer:

The area of the base is 12.56 units squared.

Step-by-step explanation:

The volume formula of a cone is $\pi r^{2} \frac{h}{3}$ . To solve for the base area, just multiply the volume by 3 and divide by the height. 25.12 * $\frac{3}{6}$ = $\frac{25.12}{2}$ = 12.56 units squared.

Which length is closest to 4.2lb

The given data is a linear dataset.

So, we start by calculating the slope (m)

$m =\frac{y_2 - y_1}{x_2 - x_1}$

Pick any two corresponding points from the table

So, we have:

$(x_1,y_1) = (8,1.21)$

$(x_2,y_2) = (12,1.63)$

So:

$m =\frac{y_2 - y_1}{x_2 - x_1}$

$m =\frac{1.63 - 1.21}{12 - 8}$

$m =\frac{0.42}{4}$

$m =0.105$

The linear equation is then calculated using:

$y = m(x - x_1) + y_1$

This gives:

$y = 0.105 * (x - 8) + 1.21$

Open bracket

$y = 0.105x - 0.84 + 1.21$

$y = 0.105x + 0.37$

To get the length closest to 4.2lb,

we set $y = 4.2$

Then solve for x

So, we have:

$y = 0.105x + 0.37$

$4.2 = 0.105x + 0.37$

Collect like terms

$0.105x= 4.2 - 0.37$

$0.105x= 3.83$

Solve for x

$x= 3.83/0.105$

$x\approx 36.5$

Answer:

3,925 feet ^2

Step-by-step explanation:

75 ft

80*

A = pi*r^2

pi * 75^2 = 17662.5

80/360 = 2/9

17662.5 * (2/9) = 3925

Germany Ron 7 miles per week and increase his distances by 1 mile in each week tell tony runs 3 miles per week and increases his

Lelechka [254]

X represents the amount of weeks:
7+x for Germany and 3+2x for Tony they have to be equal for them to run the same distance:
3+2x=7+x
-3 from each side:
2x=4+x
-x from each side:
x=4
They run the same distance on the fourth week, that distance is 7+4=11

Hope this helps :)
