Answer: 7.3333
Step-by-step explanation:
Formula for the area of a circle:
A = πr² [A = area r = radius]
The radius is (half) the diameter. Since the diameter = 10cm, the radius = 5cm.
You know:
r = 5cm Substitute/plug this into the equation
A = πr²
A = π(5)²
A = 25π -> A = 25(3.14)
A = 78.5cm²
Hello,
Please, see the attached file.
Thanks.
First you can see that there are 3 numbers 160,125,and 40 you can add 125 and 40 because they are both checks so then after you add you get $165 in checks do you then subtract $125 which is how much she put in and you get $40. So, she has $-40
In her bank account meaning her back scout was decreased by $40.
