what is the the volume of a cone (in cubic inches) of raidus 5 inches and height 3 inches? use 3.14 for n. round your answer to the nearest hundredth.

Volume of cone = (1/3) * h * pi * r^2

= (1/3) * 3 * 3.14 * 5^2 = 3.14 * 25

= 78.53 in^3 (inches cubed)

Step-by-step explanation:

Memorise the formula

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
