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 nick1337

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.
