Since A (area of circle = C) is given = 148
Where we assume:
Y represents radius of the circle (r)
X represents diameter of the circle (D)
Pi (π) = 3.14
A = 2 * π * y
148 = 2 * 3.14 * y
148 = 6.28 * y
y = 148/6.28
So, y = 23.56
D = 2 * y
D = 2 * 23.56
So, D = 47.12
Assume A is unknown (not given as 148)
A = π * y^2
A = 3.14 * (23.56)^2
A = 3.14 * 47.12
So, A = 147.95 (approx. A = 148)

Answer:
12
Step-by-step explanation:
7−(−5)
=7−(−5)
=7+5
=12
18+42=60
60 is our 100%
A equation can be used to find this;
60=100%
18 = x%
We want to know what percentage 18 sixth graders is of 60.
18*100=1,800
1800/60=30
So 30% is the answer.
