Answer:
p= 44
/9
(44 over 9)
Step-by-step explanation:
2c=14 (move 5 to the other side by adding it to 9)
c=7 (divide by 2 to get c on its own)
Let's call dimes x and the quarters x+3 since we have 3 more of them.
x+x+3=45
2x=42
x=21
we have 21 dimes and 23 quarters
21*0.10=2.1
23*0,25=5.98
if we add those together it equals 8.08
The area of circle is 379.94 cm².
Step-by-step explanation:
Given,
Radius of circle = 11 centimeters
We have to calculate the area of circle.
We know that;
Area of circle = 
Here;
π = 3.14 , r = 11
Area of circle = 
Area of circle = 3.14*121
Area of circle = 379.94 squared centimeters
The area of circle is 379.94 squared centimeters.
