Question

make a subject of the formula r =√ a/3

Answer 1

Step-by-step explanation:

Given Make a subject of the formula r =√ a/3

• We need to make a subject of the for a mula given r = square root a / 3
• Given r = √a / 3 -------------1
• Now we can find a.
• Squaring the given equation 1 we get
• So r^2 = (√a / 3)^2
• So r^2 = a / 9
• Therefore a = 9 r^2

Answer 2

Answer: 3(r²)

Step-by-step explanation:

r= √a/3

We get rid of the square root so then it’s

r²=a/3

Then because it’s a fraction we have to multiply the other side with brackets and the 3.

So now it’s

3(r²)

And that’s the answer sorry if I didn’t describe it clearly lmao :)
