Answer:
h=12 ft
volume = 314 ft^2
Step-by-step explanation:
height = 12ft
pythagorous a^2 + b^2 = c^2
=h^2 + 5^2 = 13^2
h^2= 144
h=12 ft
volume = 1/3 * pi*r^2*h
=1/3*3.14*5^2*12
=314ft^2

Answer:
Perpendicular height = 12 feet
Volume = 31.4 ft^3
Step-by-step explanation:
To find perpendicular height:
By Pythagoras theorem:
AB^2 + BC^2 = AC^2
⇒ AB^2 + 5^2 = 13^2
⇒ AB^2 + 25 = 169
⇒ AB^2 = 169 - 25
⇒ AB^2 = 144
⇒ AB = √144
⇒ AB = 12
∴ Perpendicular height = 12 feet
To find volume:
Volume of cone = π x r^2 x h/3
= 3.14 x 5^2 x 12/3
= 3.14 x 25 x 4
= 3.14 x 100
= 31.4 ft^3
∴ Volume = 31.4 ft^3
