The slant height of a cone is 8.45cm and the diameter of the base is 14cm.
Calculate, three significant figures, the
curved surface area of the cone (Take
= 22÷7

Calculate the curved surface area of the cone .

Curved surface area of cone = πrl

First of all,

Radius = Diameter/2

=> Radius,r = 14/2

=> Radius,r = 7 cm

Now,

Hence,the Curved surface area of cone is 185.9 cm².

the furthest the dog can be is 508 meters away from the house, and the closest he can be is 492 meters away from the house.
