What is the diameter of a circle whose circumference is 907.46

Mathematics

Answer:

d = 289

Step-by-step explanation:

The circumference is given by

C = pi *d

907.46 = pi *d

Using 3.14 for pi

907.46 = 3.14 d

Divide each side by 3.14

907.46 /3.14= 3.14 d/3.14

289 = d

Answer & Step-by-step explanation:

Circumference=d\pi

In order to find the diameter, then we will have to rearrange the equation.

d=\frac{Circumference}{\pi }

Now, let's plug in our numbers to solve for the diameter, <em>d</em>. We will use 3.14 for pi.

d=\frac{907.46}{3.14 }

d=289

So, the diameter of the circle is 289 units.

Sam and Bethan share £54 in the ratio of 5:4 work out how much each gets
Sindrei [870]
Answer:
Sam gets £30 and Bethan gets £24.
Why?
When dealing with ratios, add up the numbers in the ratio.
5 + 4 = 9
Now, divide the total amount of money by that number.
£54/9 = 6
Now you have the base rate. Multiply each quantity in the ratio by this number.
5*6 = 30
4*6 = 24
Now, the ratio is (in euro) 30:24. This means that Sam has £30 and Bethan has £24.
Check:
30 + 24 = 54
