Answer:
Question 1- 288.48
Step-by-step explanation:
depending on how they round your answer the number might look different.
V= Bh which means (pi)r^2(h)
3.14 x 1.25^2 x 4.9
V=24.040625 ~ 24.04
12 x 24.04
=288.48
Since the triangle is equilateral, QR = RS = QS.
a. MS = (1/2)74
MS = 37
b. Half of the equilateral triangle makes a right triangle. Use Pythagorean Theorem to find QM.
a^2 + b^2 = c^2
37^2 + b^2 = 74^2
1369 + b^2 = 5476
subtract 1369 from both sides
b^2 = 4107
take the square root if both sides
b = 64.1
QM = 64.1
The answer is: [C]: " (x - 4) " .
