Answer

15.7 meters squared.

Step-by-step explanation:

First you have to find the area of the small circle, using the formule A = 3.14(radius squared). So, 3.14(4) =12.56. Then you have to find the area of the bigger circle. A = 3.14(3 squared). A = 3.14(9) = 28.26. Finally, you subtract the area of the smaller circle from the bigger circle. 28.6 meters - 12.56 meters = 15.7 meters squared.

What is the common difference of the arithmetic sequence 5, 8, 11, 14?
AnnZ [28]

Answer:

The common difference is 3

Step-by-step explanation:

we know that

In an <u>Arithmetic Sequence</u> the difference between one term and the next is a constant called the common difference

we have

5,8,11,14

so

a1=5

a2=8

a3=11

a4=14

a2-a1=8-5=3

a3-a2=11-8=3

a4-a3=14-11=3

therefore

The common difference is 3

Six - two times twelve plus five
fomenos

Answer:

Ok, so the equation would be 6-2*12+5. The answer to that is -13.

Step-by-Step Explanation:

You would use PEMDAS. First, you multiply 2 and 12 and that's 24. Now your equation is 6-24+5. Then you subtract 6 and 24 and that's -18. Now your equation is -18+5, and the answer to that equation is -13. I hope this helps you!!

Find m of ZX<br> in circle P.<br><br> 70<br> 95<br> 155<br> 205
denis-greek [22]
The answer is C. 155

First find the measure of arc YZ.

The arc of WYZ is equal 180 degrees. So first add 25 to 85. Then subtract that to 180.

25+85=110

180-110=70.

Next add 70 to 85 since you want to find the measure of ZX.

70+85=155

So measure of ZX is equal to 155 degrees
