Question

16. Owen and Emily have circular mirrors hanging in their bedrooms. The radius ofEmily's mirror is 8in and Owen's is loin. What is the difference in the areas oftheir mirrors?

Answer 1

`\text{Area of a circle =}\pi* r^2`
`\begin{gathered} \text{Difference in areas = Area of Owen's mirror - Area of Emily's mirror} \\ R\text{adius of Owen's mirror=10in } \\ \text{Radius of Emily's mirror = 8in} \\ \pi=3.14 \end{gathered}`
`\begin{gathered} \text{Difference in areas = (}3.14x10^2)-(3.14*8^2) \\ =314-200.96 \\ =113.04in^2 \end{gathered}`
