The surface area of a cylinder consists of the two circles on either end, and the curved area around the middle. The circles have radii of 1.5 inches, so an area of pi*r^2 = 3.14 * 1.5^2 = 7.065 square inches.
The curved area can be thought of as a rectangle, like a label wrapping round the cylinder. The length of the rectangle is 5 inches, and the width of the rectangle is the circumference of one of the circles, 2*pi*r = 2 * 3.14 * 1.5 = 9.42 inches. The area of the rectangle is 9.42 * 5 = 47.1 square inches.
Putting all that together, the surface area is 7.065 + 7.065 + 47.1 = 61.23 square inches.
Answer:
Compressions
Step-by-step explanation:
The third type is compressions
Your answer is:
(125 - 8x^3) / (25 + 10x + 4x^2) = - ((2x - 5) * (4x^2 + 10x + 25)) / (4x^2 + 10x + 25) = - (2x - 5) = - 2x + 5
The correct result would be - 2x + 5.
1/2 m - 3/4 n = 16
1/2 m - 3/4 (8) = 16
1/2 m - 6 = 16
1/2 m = 16 + 6 = 22
m = 2 x 22 = 44
