3.141 * 15^2 * 18/3 = 4240.35

Since $$3.141*15^2 * \frac{18}{3} = 3.141 * 225 * 6$$ (1)

$$= 3.141*5 * 45 * 2 * 3$$(2)

$$= 3.141 * 45 * 3 * 10$$(3)

$$= 31.41 * 135$$(4)

$$= 4240.35$$(5)

Note that from step 3 or 4, we found that we don't need to round it to the nearest hundredth because that is what the answer is in and step 5 tels us the answer.
