If n = 3.14, find n^3 to the nearest hundredth.

(A) 3.10

(B) 30.96

(C) 309.59

(D) 3095.91

(E) 30959.14

Rounding decimals is very similar to rounding other numbers. If the thousandths place of a decimal is four or less, it is dropped and the hundredths place does not change. For example, rounding 0.643 to the nearest hundredth would give 0.64.

If the thousandths place is five through nine, the hundredths place is increased by one. The decimal 0.646 rounded to the nearest hundredth is 0.65.

Option B

3.14 = √10 (approx)

So, 3.14^3 = (10)^3/2 = 10√10 = 31.4 (approx)

Closest Ans is B

(A) 3.10

(B) 30.96

(C) 309.59

(D) 3095.91

(E) 30959.14

Sine we see that 3^3 = 27, and 3.14^3 will be close in value to 27, the correct answer is 30.96.
