<u>We are given</u>
- Radius of Earth; 6.4 x 100 meters = 640 meters
Clearly, the shape of the earth is a sphere. Thus, to determine the volume of the earth, we will use a formula that determines the volume of a sphere.

When we substitute the radius in the formula, we get;


Take π as 3.14


Simplify the numerator;


Divide the numerator by 3;


since u know that there is 60 minutes in a hour do 60 times 3 and u will get 180.then do 180 divided by28 and u will get ur final answer which is 6 minutes and 12 seconds
I’ll answer this later but use an equation 180 degrees
5/6 - x = 8/15
5/6 - 8/15 = x
25/30 - 16/30 = x
9/30 reduces to 3/10 = x <==Armand burned 3/10 of a row
Answer:
4 4/9 days.
Step-by-step explanation:
You work in rates per day, so:
1/10 + 1/8 = 1/x where x is the number of days working together.
Multiply through by the LCD 40x:
4x + 5x = 40
9x = 40
x = 40/9 = 4 4/9 days.
