37. Read the text carefully and answer the questions: Once upon a time in Galabal, he was a comb seller. During the lackdown period in the year 2020, his sites were almost lost. So, he started selling corn grains online through Amazon(by the way, dont suie me), and Flipcart, just understand how many grains he will have from one corn cob, he started councing them. Being a student of mathematics let's calculate it mathematically Let's assume that one com cob (see Fig), shaped somewhat like a cone, has the radius of its broadest end as 2.1 cm and length as 20 cm.
(i) Find the curved surface area of the com cub.
(ii) What is the volume of the com cub? (iii) If each 1 c * m ^ 2 of the surface of the cob carries an average of four grains, find how many grains you would find on the entire cob?
or
how many such cobs can be stored in a cartoon of size 20mmx25mmx20mm
