Answer:
![94.2m^2](https://tex.z-dn.net/?f=94.2m%5E2)
Step-by-step explanation:
The formula for SA of a cone is...
![\pi (r)(h)+\pi (r)^2](https://tex.z-dn.net/?f=%5Cpi%20%28r%29%28h%29%2B%5Cpi%20%28r%29%5E2)
Fill in what you have
![\pi (3)(7)+\pi (3)^2](https://tex.z-dn.net/?f=%5Cpi%20%283%29%287%29%2B%5Cpi%20%283%29%5E2)
Pi is 3.14 for our purposes
![\pi (3)(7)+\pi (3)^2\\3.14(3)(7)+3.14(3)^2](https://tex.z-dn.net/?f=%5Cpi%20%283%29%287%29%2B%5Cpi%20%283%29%5E2%5C%5C3.14%283%29%287%29%2B3.14%283%29%5E2)
Then solve
![21(3.14)+9(3.14)\\\\94.2m^2](https://tex.z-dn.net/?f=21%283.14%29%2B9%283.14%29%5C%5C%5C%5C94.2m%5E2)
Answer:
x = 11°
Step-by-step explanation:
The parallel lines suggest we look to the relationships involving angles and transversals. The angle marked 33° and ∠CAB are alternate interior angles, hence congruent:
∠CAB = 33°
5x is the measure of the external angle opposite that internal angle and angle 2x of ΔABC, so it is equal to their sum:
5x = 2x + 33°
3x = 33° . . . . . . . . . subtract 2x
x = 11° . . . . . . . . . . . divide by 3
Answer:
You are given such data:
In the 12th grade total of 48 students, only 13 students participate in at least one extracurricular activity and 48 - 13 = 35 students do not participate.
In 11th grade total of 106 - 48 = 58 students, 37 students participate in at least one extracurricular activity and 58 - 37 = 21 students do not participate.
<em>good luck, i hope this helps :)
</em>
Solving this inequality:
-6>t-(-13)
solve as an equation;
6>t+13
6-13>t
-7>t
-7 is greater than t, which means that can be any number smaller that t, fir instance -8, -22 etc.
Answer:
a 48 because it is a multiple of 12
