Y=9(x^2+3x-x-3)
y=9(x^2+2x-3)
y=9x^2+18x-27
Answer:
B. 100π
Step-by-step explanation:
The surface area of a sphere is given by
SA = 4 pi r^2
The radius is 5
SA = 4 * pi * r^2
SA = 4 * pi * 25
SA = 100 pi
1600÷2... 800
-------- = ----------
1654÷2.... 827
I feel Iike the answer but I kinda don’t understand it 2.4
