Question

if the radius of the circle increases three times then the diameter of the circle increases by how many times​

Answer 1

r is the radius of the circle . If the radius of a circle is increased to 3 times . Therefore the circumference of the increased by 3 times .

So,3 X 3 =6

Answer 2

Answer:

3 Times.

Step-by-step explanation:

We Know that,

Diameter=2*Radius or 2×Radius.

Then if radius increases 3 times, then,

• Diameter=2×3×Radius.

or

• Diameter=3×2×Radius.----(I)

We also know that Diameter=2×Radius(given above)

So substituting Diameter in place of 2×Radius in (I),

Diameter=3×Diameter

Hence, When Radius is tripled Diameter is also increased 3 times.
