What happens to the area of a circle when the diameter is tripled?

The new area is 4 times larger.

What happens to the area of a circle when you double the radius?

So the area is quadrupled in this case.

What will be the ratio of the circumference to the diameter of the circle if its original radius is tripled?

Solution : Let the Original Radius be r. But after tripled. ∴ Ratio will be 22 : 7, if it will tripled.

When the radius of a circle triples does its circumference triple?

If you triple the radius, the circumference also triples because r and C are directly proportional.

What happens to the area of a circle if its diameter is?

The formula for calculating the area of a circle is A = π​r​2 where pi (π) equals 3.14 and the radius (​r​) is half the diameter. The first step for calculating the area of a circle from its diameter is to find that diameter. To solve for area, square the radius (radius times radius) then multiply by 3.14.

What happens to the circumference of a circle when you triple the radius?

How does the change in the diameter affect the circumference?

As the diameter increases, the circumference of that circle also increases. As the diameter decreases, the circumference of that circle also decreases. This change occurs because the diameter is the length of the widest part of the circle (the maximum distance from one point on a circle to another.

What will be the ratio of circumference to the diameter of a circle?

Pi
Circles are all similar, and “the circumference divided by the diameter” produces the same value regardless of their radius. This value is the ratio of the circumference of a circle to its diameter and is called π (Pi).

When the circumference and area of a circle are numerically equal then the diameter is numerically equal to?

Hence,the diameter of the circle is 4 units.

What happens to the circumference and the area of a circle when you triple the radius?

Explanation: Let r be the original radius. Finally the circumference will be tripled.

What happens to the area of a circle when the diameter is halved?

1 Expert Answer When the radius is halved, your area will be divided by 4. If you think about it, radius is already half of the diameter so your area is already divided by 2, so if you cut the radius is half again, your area will be divided by 4.
