Question

Radius of circular base of an ear of corn is 6.6 cm and its length is 11.2 cm . If on an average 1 sq.cm are contains 2 corn kernels , find the total number of kernels on a cone ?

Answer 1

Answer:

Total number of kernels on corn 766 kernels

Step-by-step explanation:

we can consider a corn as a cylinder

Here base diameter is  is 6.6 cm and its length is 11.2 cm

To find volume of cylinder

Volume of a cylinder with base radius r and height h is given by,

V= πr^2h

Radius r = 6.6 cm

Height h = 11.2 cm

Volume, V= πr^2h =3.14 x 6.6 x 6.6x11.2 = 1531.92 square cm

average 1 sq cm area contain 2 corn kernels

Total number of kernels on corn =  Total volume/2

Therefore,

Total number of kernels on corn = 1531.92 /2 ≈766 kernels
