Make sure you know the formula pertaining to the question.
1. c=2(pi)(r)
2. c=2(pi)(d)
r= radius
d= diameter
c= sircumference
So we are given that the circumference of a circle is 12.3pi and the radius is unknown.
So let's plug in the known values
**we use the formula with the radius, becuase we are looking for the radius.
c=2(pi)(r)
12.3(pi)=2(pi)(r)
divide each side by pi
12.3=2(r)
divide each side by 2
r=6.15 in.
Answer:
3.45
Step-by-step explanation:
24.84/7.2 = 3.45
Let
x ----> kilograms of strawberries that Sheldon picks in the morning
y ---> kilograms of strawberries that Sheldon picks in the afternoon
so
we have that
x=y-1 2/5
x=2 1/4 kg
substitute
2 1/4=y-1 2/5
Convert mixed numbers to an improper fraction
1 2/5=1+2/5=7/5
2 1/4=2+1/4=9/4
substitute
9/4=y-7/5
y=(9/4)+(7/5)
y=(45+28)/20
y=73/20 kg
Adds kilograms in the morning and afternoon
x+y=(9/4)+73/20)
x+y=(45/20)+(73/20)
x+y=118/20 kg
Convert to mixed number
118/20=100/20+18/20=5+18/20=5+9/10=5 9/10 kg
therefore
<h2>The answer is 5 9/10 kg</h2>
