Answer:

See below,please

Explanation:

Question 1

Because we know

$b = \pi {r}^(2) + c$

So,

$\pi {r}^(2) = b - c$

${r}^(2) = (b - c)/(\pi)$

$r = + or - \sqrt{ (b - c)/(\pi) }$

Hence, the last choice is the right answer.

Question 2

Because we know

$d = \sqrt{ (h)/(6.752) }$

So,

$(h)/(6.752) = {d}^(2)$

$h = 6.752 * {d}^(2)$

Hence, the First choice is the right answer.
