Volume: 2112.5π
Surface Area: 663π
First, let's find the height of the cylinder. Using the formula for lateral surface area, 2*π*r*h:
2*π*13*h = 325π
(divide π by both sides)
26h = 325
h = 12.5 in.
Next, let's solve the surface area of the cylinder using the formula π*r²*h.
π * 13² * 12.5 = π * 169 * 12.5 = 2112.5π.
Next, let's solve the surface area using the formula 2πrh + 2πr².
(2 * π * 13 * 12.5) + (2 * π * 13²) = 325π + 338π = 663π.
Answer
35.5 hours per week
Step-by-step explanation:
532.5/15=35.5
therefore 35 and half a hour per week
Answer:
(x+5)^2
Step-by-step explanation:
(x+5)^2 Using the foil method 5+5=10 and 5x5=25
Y = mx + c
gradient = -6-9/-8-4
= -15/-12
= 1.2
when x = 4 and y = 9,
9 = 1.2(4) + c
c = 9 - 4.8
= 4.2
The slope of the line is y = 1.2x + 4.2 .
