Answer:
1520.5 cm³
Step-by-step explanation:
Volume formula for cylinder: V = πr²×h
Radius = 11 ÷ 2
= 5.5cm
Volume = π × 5.5² × 16
=1520.5cm³
Yes, the student's theory is correct, because the survey shows that the seventh graders spend more time playing games on the weekend than the eighth graders.
You would solve it in two parts.
4*n = 44 Divide by 4
4n/4 = 44/4
n = 11
=============
z^m * z^2 = z^9
When the bases are the same (on the left) the powers on the left add
m + 2
The powers on the left side of the equation are the same as the powers on the right when the bases are the same.
m + 2 = 9 Subtract 2 from both sides.
m + 2 - 2 = 9 - 2
m = 7
=================
Answers
m = 7
n = 11
8.5x2=17
20.6-17=3.6
3.6-1.37=1.23
1.23-0.75=0.48
0.48/4=0.12
