Step-by-step explanation:
Radius of the quarter circles are 4.5
pi*r^2
pi*4.5^2=63.6172512352
81-63.6172512352=17.3827487648
x=5
45,54
An equivalent division problem would be 6/16.
To make an equivalent expression, you simply multiply the same value to both sides of the fraction. (or apply the same ratio.)
