<u>Answer:</u>
<h2>(4, 6)</h2>
<u>Explanation:</u>
x = -4 + (12 - (-4))/2
x = -4 + (12+4)/2
x = -4 + 16/2
x = -4 + 8
x = 4
y = 2 + (10 - 2)/2
y = 2 + 8/2
y = 2 + 4
y = 6
the coordinates of the center of the circle: (4, 6)
Answer:
A
Step-by-step explanation:
Cylinder volume= V = π r ^2 h
So you times Pie by the radius (diametre divided by two- 3.5) you then square this. After that, times it by the height (10)
So the volume is 384.85.
You then find 30% of this, so times 384.85 by 30%.
You then get an answer of 115.455, and this is equal to A.
I hope this helps, have a lovely day.
