The equation of the circumference of a circle in terms of \pi is 2\pi r or \pi d.

The circumference for a circle with diameter 10 is 10\pi.

The circumference for a circle with diameter 19 is 19\pi.

The circumference for a circle with diameter 30 is 30\pi.

The circumference for a circle with diameter 16 is 16\pi.

Relatively easy, right?

The equation of the area of a circle in terms of \pi is \pi r^2.

The area of a circle with radius 5 is 25\pi.

The area of a circle with radius 9.5 is 90.25\pi.

The area of a circle with radius 15 is 225\pi.

The area of a circle with radius 8 is 64\pi.

Hope this helped!

(By the way, I don't know why you're using hard formulas for trying to find the radius or diameter. The diameter is simply twice the radius, and the radius is simply half the diameter.)

Answer:

Circumference = 10\pi, 19\pi, 30\pi, 16\pi

Area = 25\pi, 90.25\pi, 225\pi, 64\pi

Step-by-step explanation:

For the first row we have the radius which is 5, the diameter is 10. The formula for circumference is 2\pir. So for this one its gonna be 2\pi5 or 10\pi

radius = 5

diameter = 10

circumference = 2\pi5 or 10\pi

area = \pi5^{2} or 25\pi

for the second row

radius = 9.5

diameter = 19

circumference = 2\pi9.5 or 19\pi

area = \pi9.5^{2} or 90.25\pi

for the third row

radius = 15

diameter = 30

circumference = 2\pi15 or 30\pi

area = \pi15^{2} or 225\pi

for the fourth row

radius = 8

diameter = 16

circumference = 2\pi8 or 16\pi

area = \pi8^{2} or 64\pi

Your office needs to deliver products to various sites in your town. You can hire a firm to make those deliveries for $200 per m
Zigmanuir [339]
Hire firm:
200+0.50*1200 each month
200+600=800

lease truck:
350+480 each month
=830

so with contracting a firm instead of leasing trucks you would save 30$ each month or 30*12=360$ each year

Answer pleaseeeeeeeeee
katovenus [111]

Answer:

y=-\frac{8}{7}x+4

Step-by-step explanation:

A line is perpendicular to another if its slope is the negative reciprocal of the other.

Your lines are in slope intercept form here, y=mx+b, where m is the slope. We can see the given line has slope \frac{7}{8}. The negative reciprocal of that is -\frac{8}{7}, which is the slope of the third answer choice.
