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:
C
Step-by-step explanation:
<h2>—Math</h2>
38% = 38/100
= 19/50
Area = area of rectangle - area of 2 hemispheres
= 24 * 32 - pi * 12^2
= 315.6 sq units
X = 18
if you need the steps i could give them to you just ask!
Hope that helped!
