If the circumference of a circle is increased by 50%, then its area will be increased by (a) 100% (b) 125% (c) 150% (d) 75%​
Svetradugi [14.3K]

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

\frac{A_{1} }{A_{2} } =(_{} \frac{I_{1} }{I_{2\\ ^{~2~} }}

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

l_{2} = l_{1} + 0.5l_{1} =1.5l_{1}

Now subtracting from the original area then  

2.25 - 1=1.25

This means that the area was increased by 1.25, which means 125%

 

Hence option B is the correct answer

The scatter plot below shows the relationship between the diameter (x), in mm, and mass f(x), in grams, of a berry: ordered pair
kkurt [141]
The function would be f (x) = 0.4x - 4.

Explanation
We can see that this is linear, since it increases at a constant rate.  We find the slope using the formula
m=(y₂-y₁)/(x₂-x₁) = (0.8-0.4)/(12-11) = 0.4/1 = 0.4

We use point-slope form to write the initial equation:

y-y₁ = m(x-x₁)
y-0.4 = 0.4(x-11)

Using the distributive property:
y-0.4 = 0.4*x - 0.4*11
y-0.4 = 0.4x-4.4

Add 0.4 to both sides:
y-0.4+0.4 = 0.4x-4.4+0.4
y=0.4x-4
