Answer:

119.32 miles

Step-by-step explanation:

C = 2πr

Input the data given.

C= 2× 3.14×19

2×3.14= 6.28

6.28×19= 119.32

Therefore, the circumstance would be 119.32 miles.

Which equation represents the line that passes through the point (1,5) with a slope of-2

svlad2 [7]

Answer:

The equation of the line would be y = -2x + 7

Step-by-step explanation:

In order to solve this, use the point and the slope in point-slope form. Then solve for y.

y - y1 = m(x - x1)

y - 5 = -2(x - 1)

y - 5 = -2x + 2

y = -2x + 7

If a cylinder with height 9 inches and radius rr is filled with water, it can fill a certain pitcher. How many of these pitchers

katrin2010 [14]

Answer:

9 pitchers

Step-by-step explanation:

Given

Cylinder 1:

$Radius = r$

$Height = 9$

Cylinder 2:

$Radius = 3r$

$Height = 9$

Required

How many pitchers' cylinder 2 can fill

First, we calculate the volume of both cylinders

Volume is calculated as:

$Volume = \pi r^2h$

For A:

$V_A = \pi r^2*9$

$V_A = 9\pi r^2$

For B:

$V_B = \pi (3r)^2 * 9$

$V_B = \pi *9r^2 * 9$

$V_B = 9* 9\pi r^2$

In (a): $V_A = 9\pi r^2$

So, we have ve:

$V_B = 9*V_A$

$V_B = 9V_A$

<em>If the first cylinder can fill 1, then the second can fill 9 pitchers</em>
