Answer:
Hi, There!
Option B 125% Is the Most Accurate Answer
Step-by-step explanation:
Circumference is the distance around a plane shape. So, it also measures length.
Length and area of two similar shapes are related by the formula
Where the A in both cases represents area and the L represents length. But here the Ls will represent circumference.
Since the circumference of the circle increased by 50%, then the new circumference becomes
Now subtracting from the original area then
This means that the area was increased by 1.25, which means 125%
Hence option B is the correct answer
Answer:
y = - x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = =
= -
note the line crosses the y- axis at (0, 2) ⇒ c = 2
y = - x + 2 ← equation of line
