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

Elliot is riding in 100 mile bike race to raise money for charity so far he has completed 7/10 of the race how far has Elliot bi

Dmitry_Shevchenko [17]

Answer:

Elliot biked 70 miles

Explanation:

We are given that the total distance of the race is 100 miles

We are also given that Elliot covered $\frac{7}{10}$ of this distance

To get the number of miles covered by Elliot, we will simply multiply the ratio of the covered distance ( $\frac{7}{10}$ ) by thetotal distance of the race (100 miles)

This is done as follows:

Distance covered = $\frac{7}{10}$ $* 100 = 70$ miles

Therefore, Elliot biked for 70 miles

Hope this helps :)
