find the volume of cone if the radius of its base is 1.5 cm and its perpendicular height is 5 cm
Answers
Answer:
Volume of cone = 35.35 cm³
Step-by-step explanation:
Given---> Radius of the base of cone is 1.5cm and perpendicular height of cone is 5cm.
To find----> Volume of cone
Solution---> ATQ,
Radius of base = 1.5cm
perpendicular height = 5cm
Volume of cone = π r² h
Where , r = radius of base of cone
= 1.5 cm
h = Height of cone
= 5 cm
So
=> Volume of cone = ( 22 / 7 ) × ( 1.5 )² × 5
= ( 22 / 7 ) × 2.25 × 5
= ( 22 × 5 × 2.25 ) / 7
= ( 110 × 2.25 ) / 7
= 247.50 / 7
= 35.35 cm³
Additional information--->
1) Curved surface area of cone = π r l
2) Total surface area of cone = π r ( r + l )
3) Area of base of cone = π r²
4) Volume of cylinder = π r² h
5) Curved surface area of cylinder = 2 π r h
6) Total surface area of cylinder = 2 π r ( r + h )
7) Area of base of cylinder = π r²
8) Volume of sphere = 4/3 π r³
9) Surface area of sphere = 4 π r²

base =1.5 cm
h=5
a/q
volume of cone =1\3×π×r²× h
= 1/3×22/7×(1.5 )²×5
