Answer:
8 feet.
Step-by-step explanation:
The formula for volume of a cylinder is (using 3.14 for
). So it would be
times 7 times 3.14 which equals
times 21.98. 1406.72 divided by 21.98 is 64. The square root of 64 is 8. The radius is 8.

Answer:
B
Step-by-step explanation:
The maximum value of the function is the y- coordinate of the vertex.
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
= -
y = - 3x² - 15x + 9 ← is in standard form
with a = - 3 and b = - 15, thus
= -
= - 2.5
Substitute x = - 2.5 into the equation for y- coordinate of vertex
y = - 3(- 2.5)² - 15(- 2.5) + 9 = - 18.75 + 37.5 + 9 = 27.75 → B
Answer:
31) They divided by 100, they're suppose to times 0.86 by 100 instead, which will be 86%
33) 0.34 x 100=34%
35) we do the inverse to turn it back into
a decimal which will be 0.36
36) 16.24÷100=0.6424
