Answer:
Half; twice
Step-by-step explanation:
In a circle, the radius is said to be the distance from the center of the circle to any point on the edge of the circle, it is denoted as "r". The radius is called a radii if it is more than one.. The radius of a circle is half the length of the diameter of a circle because the diameter of a circle is the distance of the line that passes through the center of a circle touching both edges of the circle. It is denoted as "d".
Thus,
2r = d
r = d/2
For example, if the radius of a circle is 10cm, the diameter of the circle will be calculated as: d = 2 * 10 = 20cm. Which means if the radius is 10cm, diameter will be 20cm.
Therefore, the radius of a circle is half the length of its diameter. the diameter of a circle is twice the length of its radius
Jessica runs fastest because her time/second is about 10 seconds while brookes is around 12.
15) factor out cos: cos(x)(sin(x)+1)=0
Now this is true when either cos(x)=0 (x=pi/2 and 3pi/2)
Or when sin(x)=-1 (x=3pi/2)
So it's solutions are pi/2 and 3pi/2
Answer:
School collected 273 coats in second month.
Step-by-step explanation:
Given
Total number of coats collected in 2 months = 542
Number of coats collected in first month = 269
We need to find the number of coat school collected in second month.
Solution:
Now we can say that;
Total number of coats collected in 2 months is sum of Number of coats collected in first month and Number of coats collected in Second month.
Also We can say that;
Number of coats collected in Second month is equal to Total number of coats collected in 2 months minus Number of coats collected in first month.
framing in equation form we get;
Number of coats collected in Second month = 
Hence School collected 273 coats in second month.
The answer is 37.8541178
hope this helps ;)
