Step-by-step explanation:
equation format: y = mx + b where m is slope and b is the y intercept.
From the points given we find that it is a horizontal line, which means slope or m = 0. So we know so far:
y = 0x + b or y = b
The y-intercept occurs where x = 0. This occurs at y = -7. So the equation for these two points:
EQUATION: y = -7

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
