To determine the type of product resulting from multiplying \( 35 \) and \( 3\pi \), we can follow these steps:
-
Identify the nature of the numbers:
- \( 35 \) is a whole number (and also a rational number).
- \( 3\pi \) involves \( \pi \), which is an irrational number. Therefore, \( 3\pi \) is also irrational.
-
Multiply the numbers:
- The product \( 35 \times 3\pi = 105\pi \).
-
Determine the nature of the product:
- The product \( 105\pi \) includes an irrational number (\( \pi \)) multiplied by a rational number (\( 105 \)). The product of a rational number and an irrational number is always an irrational number.
Based on this analysis, the correct response is:
an irrational number.
