The formula for finding the circumference of a circle is 2πr or <span>πd
So, there are 2 ways to find it.
1) Using the diameter, you would do </span><span>π x 14.
This will give you </span><span>43.9822971503
(round the number to however many dp it says to do :) )
2) Using the radius (half of the diameter), you could do 2</span>π x 7
which will also get you <span>43.9822971503</span>
Answer:
x = 4
Step-by-step explanation:
When a tangent and a secant are drawn from an external point to a circle.
Then the product of the external part of the secant and the entire secant and the square of the measure of the tangent are equal, hence
x(x + 5) = 6²
x² + 5x = 36 ( subtract 36 from both sides )
x² + 5x - 36 = 0 ← in standard form
(x + 9)(x - 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 9 = 0 ⇒ x = - 9
x - 4 = 0 ⇒ x = 4
However, x > 0 ⇒ x = 4

Step-by-step explanation:
Numbers may be formed with or without the repetition of digits. Let us observe some of the formation of numbers without the repetition of digits. But with the digit 0 and the digit 6, only the number 60 is formed.
