Answer:
<h2>The circumference is multipled by 4.</h2>
Step-by-step explanation:
The formula of an area of a circle"

The formula of a circumference of a circle:

The area multipled by 16:

The radius has increased fourfold, therefore:

The circumference is multipled by 4.
You can calculate the area and check the circumference:

Calculate the radius:
<em>divide both sides by π</em>

Calculate the circumference of both circles:



#4)
cross multiply
2(8x+10) = 4 * 5x
16x + 20 = 20x
4x = 20
x = 5
divide food money by income:

Answer:
4,301,970
5,149,815
Step-by-step explanation:
The cost of a bicycle is 2895
Therefore the cost of 1486 bicycles is
= 2895×1486
= 4,301,970
A truck can carry 6785 kg of food
Therefore the amount in which 759 truckj can carry can be calculated as follows
= 6785×759
= 5,149,815
Answer: 16 2/3%
Step-by-step explanation:
Given that:
Shape are either square or circle with both equally likely :
Hence,
P(square) = 1/2 ; P(circle) = 1/2
Color are either blue, red or green with the three equally likely ;
P(red) = 1/3 ; P(green) = 1/3 ; P(blue) = 1/3
Probability of creating a green circle :
Independent probability
P(green n circle) = p(green) * p(circle)
P(green n circle) = 1/3 * 1/2
P(green n circle) = 1/6
= 0.16666
(0.16666 * 100%) = 16.6666%
= 16 2/3%
