Answer:
12.9 cm ( nearest tenth )
Step-by-step explanation:
sin 40° =
( multiply both sides by 20 )
20 × sin 40° = b, hence
b = AC = 20 × sin 40° = 12.9
Volume of cone=1/3 times height times pir^2
v=15
r=3
15=1/3 hpi3^2
15=1/3hpi9
15=9/3hpi
15=3hpi
divide 3
5=hpi
h=5/pi
pi=aprox 3.14
5/3.14=1.59
1.59 ft
Step-by-step explanation:
Use a Table of Values to Graph the Equation y =3x+1. y=3x+1 y = 3 x + 1. Substitute −2 - 2 for x x and find the result for y y . y=3(−2)+1 y
