The formula for finding circumference is Pi multiplied by diameter.

3.14 x 25ft = 78.5 feet

This would round up to 79 feet in circumference.

Answer:

79 ft

Step-by-step explanation:

The formula for the circumference of a circle is

C = 2πr.  If it's the diameter that is known, then C = πd.  We will use the latter formula to find the circumference of this pool:

C = π(25 ft) = 78.54 ft, approx., which, to the nearest foot, is 79 ft

Graph ​ y=−5/6x−4 ​.<br><br> Use the line tool and select two points on the line.
postnew [5]

Given equation is y=-\frac{5}{6} x-4

If we substitute x = 0, then, y = - 4.

So, (0, -4) is a point on the line.

If we substitute x = - 6, then y = 5 - 4 = 1.

So, (-6, 1) is another point on the line.

Joining (0, -4) and (-6, 1), we get the graph of the line.

What is the area of cross-section ADGF of this right rectangular prism?
dedylja [7]

Answer:

C.52 square units

Step-by-step explanation:

We are given that

Length of cross-section ADGF,l=13units

Length of cross-section ADGF, b=4 units

We have to find the area  of cross-section ADGF of this right rectangular prism.

We know that

Area of rectangle=l\times b

Using the formula

Area of cross-section ADGF of this right rectangular prism

=13\times 4

Area of cross-section ADGF of this right rectangular prism=52square units

Option C is correct.

C.52 square units

An inlet pipe on a swimming Pool can be used to fill the pool in 36 hours. The drainpipe can be used to empty the pool in 40 hou
krok68 [10]
So 2/3 of 36 is 24. So 24 that were filled and 2/3 of 40 is 80/3 which equals 26 2/3 to drain it. And then to fill the pool would be 36 hours. What's so hard...

Slope =<br> ; y-intercept = -3
Goshia [24]

Question is incomplete Let assume the Slope = 2

Answer:

Therefore the Equation of line is

y=2x -3

Step-by-step explanation:

Given:

Slope = 2 ( Assumption )

y-intercept = -3

To Find:

Equation of Line in Slope-intercept form

Solution:

Equation of Line in Slope-intercept Form is given as

y=mx+c

Where,

m=Slope\\c=y-intercept

So, substituting Slope =2 and y-intercept = -3 in above we get

y=2\times x -3 Which is the Required Equation of line

Therefore the Equation of line is

y=2x -3
