Step 1
Ans(1) We have given
radius of circle \(\displaystyle={10}\in{c}{h}{e}{s}\)
\(\displaystyle\Rightarrow{r}={10}\) inches
As area of circle
1) \(\displaystyle{A}=\pi{r}^{{{2}}}\)
\(\displaystyle\Rightarrow{A}=\pi{\left({10}\right)}^{{{2}}}\in{c}{h}^{{{2}}}\)
\(\displaystyle{a}{r}{r}{w}{o}{A}=\pi{\left({10}\times{10}\right)}\in{c}{h}{e}{s}^{{{2}}}\)
\(\displaystyle\Rightarrow{A}={100}\pi\in{c}{h}^{{{2}}}\)
So area of circle \(\displaystyle={100}\pi\) square inches

Step 1
If the radius of the circle is 10 centimeters, the formula to get the area would be \(\displaystyle\pi{r}^{{{2}}}\), and that would give us the area of \(\displaystyle{100}\pi\) square centimeters.
\(\displaystyle{\frac{{{360}}}{{{90}}}}\) would give us 4, so \(\displaystyle{\frac{{{100}}}{{{4}}}}\) would give us the answer of 25 square centimeters

Step 1
Given Data:
The radius of the circle is: r=10inches
The area of the circle is,
\(A=\pi r^{2}\)
Step 2
Substitute the values in the above equation.
\(A=\pi(10)^{2}\)
\(=100\pi\) square inches
Thus, the exact value of the area of the circle is \(100\pi\) square inches.
