Ans. Diameter = 10.5 cm

Radius = = cm
Slant height of cone = 10 cm
Curved surface area of cone= 
= = 165 cm2
Total surface area of cone = 
= 
= = 251.625 cm2

Radius = = cm
Slant height of cone = 10 cm
Curved surface area of cone= 
= = 165 cm2
Total surface area of cone = 
= 
= = 251.625 cm2

hi here we have the radius of cone =d/2
=10.5/2 n then we have the slant height=10cm n we I'll take value of π=22/7
so apply the formula π*radius*slant height.Hope this helped you.
