A spinner has four sections. The sections are red, blue, green, and yellow. Andrea spins the spinner many times and records the
results in a table. Look at the figure.
A table with two rows and four columns is shown. The first row is Color. The second row is Frequency. Red, thirteen. Blue, nineteen. Green, twenty-eight. Yellow, ten.
Find the experimental probability of spinning each color.

Answer:
16π
Step-by-step explanation:
Given that:
The sphere of the radius =
The partial derivatives of
Similarly;
∴
Now; the region R = x² + y² = 12
Let;
x = rcosθ = x; x varies from 0 to 2π
y = rsinθ = y; y varies from 0 to
dA = rdrdθ
∴
The surface area
= 8π ( -2 + 4)
= 8π(2)
= 16π
