Answer:
B
Step-by-step explanation:
So we have the formula:
And we want to solve it for r.
So, let's first divide both sides by π and h. This will cancel out the right side:
Now, take the square root of both sides:
And we're done!
Our answer is B.
I hope this helps!
Answer:
D
Step-by-step explanation:
Remember that the sum of the interior angles of a triangle will always total 180.
Therefore:
Let’s solve for <em>x: </em>
Combine LIke Terms:
Add:
Subtract 80 from both sides:
Divide both sides by 25:
Therefore, the value of <em>x </em>is 4.
Now, to find A, we can substitute it for A.
A is measured by:
Substitute 4 for <em>x</em> and evaluate:
Hence, our answer is D.
