Question

if the diameter of the base of a cone is 48 cm and its height is 10 cm. find the curve surface area, total surface area of cone and volume.​

Answer 1

Answer:

Step-by-step explanation:2200cm  

 

radius=14, slant height =50

Curved surface area of cone=π(14)(50)=2200cm  

2

 

Total surface area of coneπr(r+l)=π(14)(14+50)=2816cm  

2

 

radius=35,height =8.4 dm=84 cm,slant height=  

r  

2

+h  

2

 

​  

=91cm

Curved surface area of cone=π(35)(91)=10010cm  

2

 

Total surface area of cone =πr(r+l)cm  

2

=π(35)(35+91)=13860cm
