Question

solve for r
A= 3r(to the 2 power) i couldn’t make it a small two

Answer 1

Answer:

$r = \sqrt[2]{ \frac{a}{3} }$

b -

$\sqrt{ \frac{300}{3} } = \sqrt{100} = 10$

Answer 2

Answer:

r = $\sqrt{\frac{a}{3}}$

Step-by-step explanation:

1. A = 3r²

(Divide 3 by both sides)

2. A/3 = r²

(Square root both sides)

√A/3 = r
