When the radius is 8, the area would be 201.06
Area of circle = pi x radius² (pi x 8²)
Answer:
(Choice B)
Step-by-step explanation:
Solve the following expression:

-Use <u>Distributive Property</u>:


-Combine like terms:


I: 635=dimes*10+quarters*25
or shorter
635=d*10+q*25
II: d=q*3+3
Substitute II (d=3q+3) into I to replace d:
635=d*10+q*25
635=(3q+3)*10+q*25
635=30+30q+25q
605=55q
11=q
-> 11 quarters
"What expression represents the number of dimes if q represent quarters"
insert q=11 into II:
II: d=q*3+3
d=11*3+3
d=33+3
d=36
