Full solution

1\times\pi\times(11.5)^{2}\times(16)

Identify Components: Identify the components of the expression. $\newline$ We have the expression $1\times\pi\times(11.5)^{2}\times(16)$ . This expression consists of a multiplication of $1$ , $\pi$ (pi), the square of $11.5$ , and $16$ .
Simplify Expression: Simplify the expression where possible. $\newline$ Since multiplying by $1$ does not change the value, we can ignore the $1$ . The expression simplifies to $\pi\times(11.5)^{2}\times(16)$ .
Calculate Square: Calculate the square of $11.5$ . $\newline$ $(11.5)^{2} = 11.5 \times 11.5 = 132.25$
Multiply by $16$ : Multiply the result from Step $3$ by $16$ . $\newline$ $132.25 \times 16 = 2116$
Multiply by $\pi$ : Multiply the result from Step $4$ by $\pi$ . Since $\pi$ is an irrational number, we will use its approximate value for calculation purposes, which is $3.14159$ . $2116 \times \pi \approx 2116 \times 3.14159$
Calculate Final Result: Calculate the final result. $2116 \times 3.14159 \approx 6647.90964$
