Answers:
1/2a= 8
Multiply by 2/1 on both sides
1/2(2/1)a= 8(2/1)
Cross out 1/2 and 2/1 equals to a
a= 16
4n= 32
Divide by 4 for both sides
4n/4= 32/4
n= 8
3x= 36
Divide by 3 for both sides
3x/3= 36/3
x= 12
m/3= 2
Multiply by 3/1 for both sides
3/1*m/3= 2(3/1)
Cross out 3/1 and 3 becomes m
m= 6
x-8= 12
Move -8 to the other side. Sign changes from -8 to +8
x-8+8= 12+8
x= 20
48= 3k
Divide by 3 for both sides
48/3= 3k/3
k= 16
13/b= 0
Multiply by 1/13 for both sides.
13/b( 1/13)= 0(1/13)
b= 0
39= 13y
divide by 13 for both sides
39/13= 13y/13
y= 3
Hello there!
We've already given the formula so I will not be adding it here.
We are also given that π = 3 for this problem.
r is defined as 'radius'
Radius is a point from center to one of endpoints.
Look at the image, the radius is given as 7cm.
From the information we gathered:
Substitute in the formula.
Cancel 3 out.
Evaluate 7^3
Multiply
Therefore, the volume is 1372.
Let me know if you have any questions!

Answer:
The answer is 68°
Step-by-step explanation:
Recall that tan ∅° = 
for a right triangle.
The value opposite to your angle is 5, and the value that is adjacent to it is 2.
In order to solve for the degree, you use tan^-1(
) on your calculator.
This gives a value of 68.19459, rounded to just 68.
