Answer:
[tex]130.624km^{3}[/tex]
Step-by-step explanation:
Given : A volcano in shape of a cone has a diameter of 16 km and a height of 1.95 km.
To Find : Volume of Volcano.
Solution :
Since we are given that volcano is in shape of cone .
So, Formula of volume of cone : [tex]\frac{1}{3} \pi r^{2}h[/tex]
Height = 1.95 km.
Diameter = 16 km
Radius (r) = Diameter/2 = 16/2 =8 km
π = 3.14
Substituting all values in formula
Volume of volcano:
= [tex]\frac{1}{3} *3.14 (8)^{2}*1.95[/tex]
⇒ [tex]\frac{391.872}{3} [/tex]
⇒ [tex]130.624km^{3}[/tex]
Thus , The volume of volcano is [tex]130.624km^{3}[/tex] i.e. 131 cubic km. nearest to whole number
