Circumference of a circle =
(diameter)
Diameter = 23 in.
Plug in the diameter = 23 in in the formula of circumference given above
Circumference of a circle =
(23)
Circumference of a circle = 23
= 3.14
Circumference of a circle = 23 (3.14)

Option D is the answer
Answer:
15 is 30% of 50
Step-by-step explanation:
We have, 30% × x = 15
Multiplying both sides by 100 and dividing both sides by 30,
we have x = 15 × 100/30
x = 50
If you are using a calculator, simply enter 15×100÷30, which will give you the answer.
