Question

radius:15 diameter:? Circumference:?
what is diameter and Circumference​

Answer 1

Answer:

Diameter = 30 ,Circumference = 94.26

Step-by-step explanation:

According to the information provided in the question it is given as

Radius =15

We need to find the Diameter and circumference

As seen from the question this is about circle

So by applying formula we get the value of diameter and circumference of circle So first understand the diameter and circumference

The Circumference is the distance once around the circle. ... When we divide the circumference by the diameter we get 3.141592654...

The Diameter goes straight across the circle, through the center.

Now formula of diameter

Diameter = D = 2 x Radius

                 D = 2 x 15

                 D =30

Now  apply formula of circumference of circle

$C =2\pi r\\C= 2\times \frac{22}{7} \times 15$

Now solving  by lowest term we get

$C=2\times 3.142\times 15$

$C= 94.26$

So diameter is 30 and circumference is  94.26
