Find the surface area of the cylinder in terms of π

304 pi in ^2

Step-by-step explanation:

The surface area of a cylinder is given by

SA  = 2 pi r^2 + 2 pi rh  where r is the radius and h is the height

SA = 2 * pi * 8^2 + 2 * pi * 8 * 11

SA = 128 pi + 176 pi

SA =304 pi

a

step-by-step explanation:

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
