Q.16 - Algebra 1

Question

Find the area or volume of each.

Step-by-Step Solution

Answer

The required area is represented by $12.56$ square meters.

Step 1. Analyze the provided figure.

The provided figure is representing a circle having radius 2 m so its area will be calculated.

Step 2. Take the help of area of circle.

Take the help of formula represented by $A=\pi r^2$ that is associated with the area of circle in which the representation of radius is $r$. So, substitute 2 in place of $r$ into the formula.

$\begin{array}{c}A=\pi {\left(2\right)}^2\\ =4\pi \end{array}$

Step 3. Determine the actual area.

Take the value of $\pi$ as 3.14 and determine the required area.

$\begin{array}{c}A=4\cdot 3.14\\ =12.56\end{array}$
