Answer:
3.81 inches
Step-by-step explanation:
πr² + 100 = π(r+3)²
divide by π and simplify:
r² + (100/π) = r² + 6r + 9
100/π = r² + 6r + 9
31.8309886184 - 9 = r² +6r
r² = 6r - 22.8309886184
0 = 6r - 22.8309886184
22.8309886184 = 6r
divide by 6:
3.80516476973 ≈ 3.81 inches
Answer:
I think so 2
Step-by-step explanation:
Answer:
As mentioned in the explanation steps.
Step-by-step explanation:
The following theorem is helpful to prove that the alternate exterior angles are congruent.
If two lines lie in the same plane and parallel to each other. A traversal line intersect these parallel lines at different points, then the alternate exterior angles must be same.
Answer:
D
Step-by-step explanation:
<u>How to find the inverse of a function.</u>
- Replace f(x) with y
- Swap x and y places. (sign doesn't matter here.)
- solve for y.
f(x) = 8√x
y = 8√x
x = 8√y
x^2 = (8√y)^2
x^2 = 64y
y = x^2 / 64
= (1/64) x^2
