Yes, the circle's area will change because the radius is different and when you go to do the formula for area the radius will not be the same it will have tripled. The area of the circle with a radius of 3 would be 28.26. The area of the circle with a radius of 1 would be 3.14. The area of a circle with radius 3 is 9 times as big as the area of a circle with radius one. So the answer is 9. Hope that helped.

What is the slope of the line shown in the graph?<br> A 3/2<br> B 2/3<br> C -3/4<br> D - 2/3
goldenfox [79]

Answer:

D. -2/3

Step-by-step explanation:

Since it is going down, it is negative

Think of this: Rise/Run

In this case, rise is when you are going up or down the graph

Run is when you are going to the right of the graph

Let's use 2 points (0,3) and (3,1)

Since you are going three points to the right we are going to put 3 in for run

You are going 2 places down, so we are going put -2 in for rise

This gives us -2/3

Another way to do this is (1-3)/(3-0) = -2/3

Find the circumference of the circle shown. Round to the nearest tenth.
Sunny_sXe [5.5K]

Answer:

110 cm

Step-by-step explanation:

So if we know the diameter, which is 35 cm, we can use the formula π*d. So we would take the diameter and put it in the place of d. So it would be pie times 35. Which would result in us getting 109.96. And this rounded to the nearest tenth would be 110. So The circumference would be 110 cm.

A sprinkler system is designed to water 5/8 acre of land in 1/4 hour. How many acres of land can it water in 1 hour?
Kryger [21]
Hi there!

If a sprinkler system can water 5/8 acre of land in 1/4 hour, it can water 20/8 acre of a land in one hour. When turned into a mixed number you get that it can water 2 & 1/2 acres of land in 1 hour.
