Answer 2

Given :

Ice cream cone has the radius of the base 2 cm height 10 cm

To Find :

Cirved surface area , Total suface area & Volume of cone

Solution :

•In cone

Radius (r) = 2 cm

Height (h) = 10 cm

slant height = L cm

L = √(h²+r²) = √(100+4) = √104 = 10.2 cm

•Now , Curved surface area of cone = πrL

Curved surface area = 22×2×10.2/7

Curved surface area = 448.8

Curved surface area = 64.14 cm²

•Now , Total surface area of cone = πr(L+r)

Total surface area = 22×2×(10.2+2)/7

Total surface area = 76.685 cm²

Total surface area = 62.8571 cm²

•Now , Volume Of cone = πr²h/3

Volume = 22×2×2×10/(7×3)

Volume = 880/21 cm³

Volume = 41.904 cm³

•Hence , curved surface area is 64.14 cm² , total surface area is 62.8571 cm² and volume is 41.904 cm³
