Answer:
A≈78.54cm²
Step-by-step explanation:
78.55cm^2
Area of a circle is given as πr^2
That's is ,
A = πr^2
Let's use π = 3.143
r = 5cm
A= 3.142 * 5^2
A= 3.142 * 25
A = 78.55 cm^2
Use distributive property to remove the parentheses:
35.36 i think
40%x68=27.2
20%x27.2=5.44
27.2+5.44=32.64
68-32.64=35.36
$35.36
