guajiro [1.7K]
We know that
[area of a circle]=pi*r²
r=10 in
[area of a circle]=pi*10²-----> 100*pi in²

if  360° (full circle) has an area of------------------> 100*pi in²
 45°-------------------------------> X
X=45*100*pi/360-----> x=12.5*pi in²

the answer is
the option B) 12.5*pi in²

What is the solution to the equation?
UkoKoshka [18]
\frac{1}{3}x+\frac{1}{3}(2x-15)=3\frac{1}{2}\\\\
\frac{1}{3}x+\frac{1}{3}(2x-15)=\frac{7}{2}\ \ \ |Multiply\ by\ 6\\\\
2x+2(2x-15)=21\\\\
2x+4x-30=21\\\\
6x-30=21\ \ |Add\ 30\\\\
6x=51\ \ \ |Divide\ by\ 6\\\\
\boxed{x=\frac{51}{6}=8\frac{1}{2}}
