Answer:

(2) 2,640 ft

Step-by-step explanation:

I'm going to assume that in this question, you are walking 1 full circle around the reservoir. That would mean you need to calculate the circumference of the circular reservoir.

The circumference formula is:

C = ⫪d

C stands for Circumference

d stands for diameter

I will use 22/7 instead of pi, so the formula looks more like this:

C = (22/7)(d)

The diameter is 840 feet, so we will substitute the variable d with 840:

C = (22/7)(840)

You can plug this part into the calculator, but by hand, it'll look something like this:

(22/7)*840 = (22*840)/7

18,480/7 = 2.640

Hope it helps (●'◡'●)

Find the area of a circle with a circumference of 6.28 units
viktelen [127]

Answer:

area of the circle = 3.14 square units

Step-by-step explanation:

Circumference of the circle formula is 2\pir

where r is the radius of the circle

given circumference = 6.28

2\pir = 6.28

Value of pi is 3.14

2*3.14 * r= 6.28

6.28 r = 6.28

divide by 6.28 on both sides

r = 1

radius = 1

Area of the circle = \pi r^2

= 3.14 *1*1 = 3.14

Solve for x.<br> x-8=-20
NeX [460]

Answer:

Step-by-step explanation:

To solve:

x - 8 = -20

Simply add +8 to both sides of the equation.

It becomes :

x - 8 +8 = -20 + 8

Note that, -8 + 8 will cancel out, and results to zero.

Therefore the equation becomes :

x = -20 + 8

x = -12.

Hope this helped!
