Question

The radius of a conical shaped ear of corn is 8cm and it's length is 15cm if 1sp.cm. area of corn contains 2 corn kernels, find the total number of kernels on a corn

Answer 1

Step-by-step explanation:

Hello Mate!

Curved surface area of corn = πrl

Now, l = √( r² + h² )

= √( 6.6² + 11.2² )

= √( 43.56 + 125.44 )

= √169 = 13 cm

So, curved surface area = 22/7 × 6.6 × 13 cm²

= 269.7 cm²

Now, when 1 cm² covers = 2 kernels

Then 269.7 cm² will cover = 269.7 × 2 = 539.4 kernels

Hence, 539 kernels ( approx. ) will be in the corn.

Have great future ahead!
