A circle has a circumference of 28.26 unites. What is the diameter of the circle?

Answers

Answer 1
Formula for finding Diameter with Circumference: d (diameter) = C (circumference) / π (pi = 3.14)

Since we know the Circumference of the circle (28.26) we can use the formula to find the Diameter of the circle

D = C/πD = 28.26/πD = 8.99543738355...D = 9 (Round it)9

The Diameter of the circle is 9

Convert the following repeating decimal to a fraction in simplest form.
.78

Answers

Answer:

78/100

Step-by-step explanation:

Since .78 is in the hundredths place just move the decimal two places to the right then put it over 100. But idk if you mistyped this because .78 is not a repeating decimal

Answer:

6/9

Step-by-step explanation:

Change 0.7878 to a fraction.

Let n = 0.7878... Multiply both sides by 100 (by 100 when there are two repeating decimal digits)

100n = 78.7878... Subtract n from 100n.

99n = 78 Divide both sides by 99

n = 78/99 but n is 0.7878..., so

0.7878... = 78/99

Similarly with 0.66...

Let n = 0.66... Multiply both sides by 10 (by 10 when there is only one repeating digit)

10n = 6.66... Subtract n from 10n.

9n = 6 Divide both sides by 9.

n = 6/9 but n is 0.66..., so

0.66... = 6/9

Step-by-step explanation:

Since the triangles are similar, then the ratios of corresponding sides are equal, that is

3x = 45 ( divide both sides by 3 )
