Question

Find the volume, curved surface area and the total surface area of
cone having base radius 35 cm and height 12 cm.
​

Answer 1

Step-by-step explanation:

volume = π*r^2*h

= (22/7)*35^2*12 = 46181.41 cm^3

curved area = 2*π*r*h

= 2*(22/7)*35*12 = 2638.93 cm^2

base area = 2*π*35^2 = 7696.9 cm^2

total area = 7696.9 + 2638.93

= 10335.83 cm^2
