Answer:
The area of a circle is pi times the radius squared (A = π r²). Learn how to use this formula to find the area of a circle when given the diameter.
Answer:
y = 2x - 3
Step-by-step explanation:
Take any tow point from the line
(x₁ , y₁) = (1 , -1) & (x₂ , y₂) = (0 , -3)
m = 2 & (1, -1)
y - y₁ = m(x -x₁)
y - [-1] = 2(x - 1)
y + 1 = 2x - 2
y = 2x - 2 - 1
y = 2x - 3
A sphere? You know this isn't really a mathematical question right?
