Answer:
1591.1
Explanation:
The area A of a circle is given by the formula
[tex]A=\pi r^2[/tex]where r is the radius of the circle.
Now in our case r = 45/2 cm and pi = 22/7; therefore,
[tex]A=\frac{22}{7}\cdot(\frac{45}{2})^2[/tex][tex]A=\frac{22\cdot45^2}{7\cdot4^2}[/tex][tex]A=\frac{22275}{14}[/tex]Converting the above in decimal form and then rounding the answer to one decimal place gives
[tex]\boxed{A=1591.1}[/tex]Hence, the area of the circle rounded to one decimal place is 1591.1 cm^2.
