<h3>How to work with ratio questions?</h3>
We are given the ratio of apples to oranges as;
A:O = 31:11
Now, we are told that there are 2940 apples and oranges in total.
Thus, the fractions of apples and oranges of the total will be;
Apple fraction = 31/(31 + 11) = 31/42
Orange Fraction = 11/42
Thus;
Number of Apples = (31/42) * 2940
Number of Apples = 2170 Apples

Answer:
144.2 cm
Step-by-step explanation:
Length of the iron rod is 7.4cm
Radius is 3.1m
Therefore the surface area can be calculated as follows
= 2πrl
= 2×3.142×3.1×7.4
= 144.2 I'm
Hence the surface area is 144.2cm
