Answer:
A
Step-by-step explanation:
Midpoints are found by averaging the coordinates.
Averaging " add all the numbers and divide by the number of numbers.
Here, there are only 2 numbers. So, you divide by 2.
(1,2) (1,-5)

We know that V= 4/3 pi r^3
So r^3= 140/ ((4/3) pi)= 33.422538
Hence r= 3.221166
SA = 4 pi r^2
= 4 pi 3.221166^2
= 130.39 cm^2
= 130 cm^2
Pi or fractions of a plate :P

Step-by-step explanation:
Answer:
Interpreting as: X=a-sqrt b X=a+sqrt b
Input:
X = a - sqrt(b) X = a + sqrt(b)
Alternate forms:
{a = (sqrt(b) + 1) X, a = X - sqrt(b), b = 0 ∨ X = -1}
{a = (sqrt(b) + 1) X, a + sqrt(b) = X, sqrt(b) (X + 1) = 0}
