The height of a cone is equal to three timesthe radius of the base. If the base has area 49 pie cm2, what is the volume of the cone?
Answers
Answer:
343pi^3
Step-by-step explanation:
Volume of a cone = 1/3(nr^2h)
n = 22/7
r = radius
h = height
Base area = area of a circle
Area of a circle = πr²
49 pi = πr²
r² = 49
r = 7
h = 7 x 3 = 21
volume = 1/3 x 21 x 7^2 = 343pi

Answers
Answer:
Solution given:
perpendicular distance =height [p]=40m
base or horizontal distance [b]=198m
Hypotenuse or zip line [h]=?
Now
By using Pythagoras law
h²=p²+b²
h²=40²+198²
h=√40804
h=202m
So the Zip line is 202m long.

Answers
Answer:
$16.70
Step-by-step explanation:
9.5 miles / .25 = 38
The first mile is 1.25 so we do this
37 * .35 = 12.95
12.95 + 1.25 = 14.2
14.2 + 1.25 + 1.25(two additional passengers) = 16.70
