Answer:
A. <u>Volume = 4,523.9 mm³ (cubic mm)</u>
B. <u>Surface area = 1,658.76 mm² (square mm)</u>
Step-by-step explanation:
A. Lest's calculate the volume of the cylinder:
r = 12 mm, h = 10 mm
Volume = π * r² * h
Volume = 3.1416 * 12² * 10
Volume = 3.1416 * 144 * 10
<u>Volume = 4,523.9 mm³</u>
B. Let's calculate the surface area of the cylinder:
Surface area = 2π * r * h +2π * r²
Surface area =2π * 12 * 10 + 2π * 12²
Surface area = 6.2832 * 120 + 6.2832 * 144
<u>Surface area = 753.98 + 904.78 = 1,658.76 mm²</u>
Answer:
$4.50 for 150 papers
Step-by-step explanation:
We have x^2 + 2 · x · (11/2) + (11/2)^2 = - 24 + (11/2)^2;
Then, ( x + 11/2 )^2 = -24 + 121/4;
( x + 11/2 )^2 + 96/4 - 121/4 = 0;
( x + 11/2 )^2 - 25 / 4 = 0;
( x + 11/2 )^2 - (5/2)^2 = 0;
( x + 11/2 - 5/2)·( x + 11/2 + 5/2 ) = 0;
( x + 6/2 )·( x + 16/2 ) = 0;
( x + 3 )· ( x + 8 ) = 0;
x = - 3 or x = -8;
The first choice is the correct answer.
