The area of a circle uses the radius of a circle, which is 1/2 the diameter.
In the calculation the radius is squared.
Since the diameter of the larger circle is twice as large the radius would be 2 times.
2 squared would be: 2^2 = 4
This means the area of the larger circle is 4 times larger which would make the ratio 4:1
Step-by-step explanation:
Standard form is of course 17,497,403.
Expanded form is:
10,000,000 + 7,000,000 + 400,000 + 90,000 + 7,000 + 400 + 3
Answer:
Step-by-step explanation:
to calculate mean add all the entries in a week ,then divide by 7(the number of days)
i give you hint
mean for week 1=(52+65+... +60)/7
-5a^2 - 7a = -a x (5a + 7)
let me know if you have any other questions
