Answer:
A =452.16 m^2
Step-by-step explanation:
The diameter is 24, so the radius is 1/2 of the diameter
r = 24/2 = 12
The area of a circle
A = pi r^2
A = 3.14 * (12)^2
A =452.16 m^2
The number -57/ 7 is a rational number.
<h3>What are rational numbers?</h3>
A rational number is a type of real number, in the form of;
p/q

Step-by-step explanation:
24x^2_54x_15=0
(12X +3 ) ( 2X _5 ) . = O
12x +3 =0
X= - 1/4
or
2x _ 5=0
X = 5/ 2
