A circular base cone has base area of 28 whole number 2/7 cm² and a slant height of 5 cm. Calculate i) radius
ii) the area of the curved surface
iii) the volume of the cone
[Take π= 3.14]

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
