Answer:
B) 120
Step-by-step explanation:
Initial problem: 90/x = 3/4
Cross multiply to get:
90*4 = 3x
360 = 3x
x = 120
Check (optional):
90/120 = 3/4
(simplify):
3/4 = 3/4 so it is correct

Step-by-step explanation:
we know that
The area of a trapezoid is equal to
we have
substitute the values
<u>Given</u>:
Given that the diameter of the hemisphere is 12.6 cm
The radius of the hemisphere is given by
We need to determine the volume of the hemisphere.
<u>Volume of the hemisphere:</u>
Let us determine the volume of the hemisphere.
The volume of the hemisphere can be determined using the formula,
Substituting the values, r = 6.3 and π = 3.14, we have;
Simplifying the values, we have;
Dividing, we have;
Rounding off to the nearest tenth, we get;
Thus, the volume of the hemisphere is 523.5 cm³
