Answer:

Step-by-step explanation:
The formula of a lateral area of a cone:

r - radius
l - lateral height
We have the radius r = 6in and the height H = 8in.
Use the Pythagorean theorem to calculate the lateral height:

Substitute:

Answer:
pulgada
Step-by-step explanation:

16 × y = 9 × 41
16y = 369
16y ÷ 16 = 369 ÷ 16

Answer:
a. 40000pi ft^3
b. 5 times
Step-by-step explanation:
a. the volume of a cylinder is pi * h * r^2
r = 20ft, h = 100ft
so V = pi * 100 * 20^2 = 40,000pi or around 125663.7 ft^3
b. to find the number of times, divide the volume by the amount of salt needed per storm then round down:
40000pi/21000 = 5.98 so 5 times. notes: depending on the teacher you might just round to the nearest integer
