The general equation for computing the circumference of a circle is 
, where C is the circumference, and d is the diameter. (You might also see the equation as 
where r is the radius, because 
)
Computing the circumferences of the two circles, we get:
.
To calculate the ratio of two numbers, we can divide one by the other. You can look at this as "How many times does the denominator fit in the numerator?"
So the circumference of the complex impact crater is 2 times greater than the circumference of the simple impact crater.

Latanya and George are saving up money because they both want to buy new bicycles. Latanya opened a savings account with $50. She just got a job and is determined to save an additional $30 a week. George started a savings account with $75. He is able to save $25 a week. Find the time (in weeks) when Latanya and George will have the same amount of money in their savings accounts.
Answer:
Latanya and George will have same amount after 5 weeks.
Step-by-step explanation:
Given:
Opening Amount in account of Latanya = $50
Amount deposited every week = $30
Let number of week be 'w'.
Total Amount in Latanya savings account will be equal to Opening Amount plus Amount deposited every week multiplied by number of week.
framing in equation form we get;
Total Amount in Latanya savings account =
Also Given:
Opening Amount in account of George = $75
Amount deposited every week = $25
Let number of week be 'w'.
Total Amount in George savings account will be equal to Opening Amount plus Amount deposited every week multiplied by number of week.
framing in equation form we get;
Total Amount in George savings account =
Now we need to number of week when both will have same amount.
Now to find number of week when both will have same amount we need to make both the equation same we get;
Hence Latanya and George will have same amount after 5 weeks.
Answer:
625 cm³ and 64000 cm³
Step-by-step explanation:
Given
x = ( cube both sides )
x³ = V
(a)
x = 25 cm , then
V = 25³ = 625 cm³
(b)
x = 40 cm , then
V = 40³ = 64 000 cm³
