Question

Make 'a' the subject of the formula r = √(a/3).

a) a = r^2 * 3
b) a = 3 * r^2
c) a = √(3r)
d) a = 3/r^2

Answer 1

To make 'a' the subject of the formula r = √(a/3), you can isolate 'a' by squaring both sides of the equation and then multiplying by 3. The correct answer is a) a = 3 * r^2.

Step-by-step explanation:

To make 'a' the subject of the formula r = √(a/3), we need to isolate 'a' on one side of the equation. Here's the step-by-step process to do that:

1. Square both sides of the equation to get rid of the square root: r^2 = a/3
2. Multiply both sides of the equation by 3 to isolate 'a': 3r^2 = a

Hence, the correct answer is a) a = 3 * r^2.
