Answer:

C) 48

Step-by-step explanation:

I'm using the PEMDAS method which means Parenthesis, Exponents, Multiplication, Division, Addition & Subtraction (its basically a way to order it)

Here we only got an exponent, a multiplication, and finally additions. So we start solving in that order.

3^3 + 1 * 9 + 12

27 + 9 + 12

26 + 12

Hope this helped

A circle with a circumference of 51 inches to find the area

Kaylis [27]

$\textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ C=51 \end{cases}\implies 51=2\pi r\implies \boxed{\cfrac{51}{2\pi }=r} \\\\[-0.35em] ~\dotfill\\\\ \textit{area of a circle}\\\\ A=\pi r^2\qquad \implies A=\pi \left( \cfrac{51}{2\pi } \right)^2\implies A=\cfrac{51^2}{2^2\pi }\implies A\approx 206.98$
