Let one number be x.
The other number is x-6
Product of the number is 55
x(x-6) = 55
x² - 6x - 55 = 0
<span> (x + 5)(x - 11) = 0
</span>x = -5 or x = 11
x = -5
x - 6 = -11
x = 11
x - 6 = 5
Answer: The two numbers are either -5 and -11 or 5 and 11.
The answer is 20.4 you just multiply 1.70 by 12
Answer:
A
Step-by-step explanation:
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.
