The formula for the circumference of a circle is 2 x Pi x R, or Pi x D.
Since we have our formula, we will need to divide.
When looking for the radius when given the circumference/area, it is important to cross out what you've divided by so you don't accidentally get confused.
Divide 120 by 3.14 and then cross out Pi from the formula, leaving us with 2 x R.
120 / 3.14 = 38.21
Divide 38.21 by 2 and then cross out 2 from the formula, giving us R.
38.21 / 2 = 19.1
Your radius is 19.1 meters.
I hope this helps!
Step-by-step explanation:
x = the number of goals of the top scorer.
y = the number of goals of the second top scorer.
z = the number of goals of the third top scorer.
x + y + z = 98
x = y + 8
y = z + 15
using the third in the second equation we get
x = z + 15 + 8 = z + 23
and now using this and the third equation in the first equation gives us
z + 23 + z + 15 + z = 98
3z + 38 = 98
3z = 60
z = 20
y = z + 15 = 20 + 15 = 35
x = y + 8 = 35 + 8 = 43
the player with the most goals scored 43 goals.
The expression that shows the temperature at the start of the day is 64 - 8 - 4
