Answer:
7
Step-by-step explanation:
Just put the numbers in order the find the number in the middle in the case that there are to numbers add the together then divide by 2
Answer:
It would be between -3 and 2
Step-by-step explanation:
cause -2.5 is greater than -3 and its less than 2
<h3>
Answer: 18pi</h3>
============================================================
Explanation:
The area 81pi square meters leads to the radius 9 meters
Use the formula A = pi*r^2 to see why this is the case. You plug in A = 81pi and solve for r to get r = 9.
-----------------
Once you know the radius, you can determine the circumference C
C = 2*pi*r
C = 2*pi*9
C = 2*9*pi
C = 18pi
The circumference is the perimeter, or distance, around the circle.
Im not sure srry
Step-by-step explanation:
Answer:
1041.27
Step-by-step explanation:
A=πrl+πr2
l=r2+h2
Solving forA
A=πr(r+h2+r2)=π·12·(12+102+122)≈1041.26829
