Answer: The total number of kernels on the ear of corn would be approximately 232.
Step-by-step explanation:
Dimensions for the given ear of corn
Radius, r= 6.6cm
Length, l= 11.2cm
Corn kernels are present on the lateral surface area of the ear of corn.
So,
Lateral surface area of the ear of corn= 2*pi*r*l= 2*22/7*6.6*11.2 =464.64cm^2
Since 1 sqcm area contains 2 corn kernels, so
Total number of kernels on the ear of corn= 464.64/2= 232.32
= 232 (approx).
