What is the radius of a circle if the area is 25 pi?

TAGS. Since the area of the triangle is 25π(which is ), the radius of the circle can be calculated as follows : Therefore, the diameter, which is twice the radius, is 10(Option B)

What is the radius of the area is 25?

Answer: The area of a circle is equal to pi times the radius squared. So that means that the radius of this circle is the square root of 25. That means that the radius is 5.

How do you find radius with pi?

You draw a circle. From that circle, you can determine both the circumference and the radius. Then the value of pi would be the circumference divided by twice the radius.

What is the radius of 24 pi?

If the area of a circle is 24π, then the radius of the circle is √24 units, or approximately 4.9 units.

How do you find the radius?

How to Find the Radius of a Circle?
  1. When the diameter is known, the formula is Radius = Diameter/ 2.
  2. When the circumference is known, the formula is Radius = Circumference/2π.
  3. When the area is known, the formula for the radius is Radius = ⎷(Area of the circle/π).

How do you find radius from area?

To find the radius, divide the area by pi, then take the square root.

What is the circumference of 22 pi?

What is this pi?

Succinctly, pi—which is written as the Greek letter for p, or π—is the ratio of the circumference of any circle to the diameter of that circle. Regardless of the circle’s size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14.

What is the diameter of a circle with an area of 16 pi?

Therefore, the diameter of Circle is 8cm.

What is the radius of 12 pi?

Explanation: If r is the radius of a circle, then its circumference is 2πr and area is πr2 . or r=12π2π=6 cm. As such radius is 6 cm and diameter being double of radius, diameter is 2×6=12 cm.

How do you find the radius from the circumference calculator?

To find the radius from the circumference of a circle, you have to do the following:
  1. Divide the circumference by π, or 3.14 for an estimation. The result is the circle’s diameter.
  2. Divide the diameter by 2.
  3. There you go, you found the circle’s radius.

What is the radius of a circle with a circumference of 22pi?

Expert-verified answer

We have been given that the circumference of circle is 22π. We also know that the circumference of a circle is the form of 2πr, where r is the radius. So, the radius of the circle is 11 cm !

What is the circumference of a 12cm circle?

The circumference of the circle = 75.4 cm.

What is the area of the radius is 8?

We know that, the Area of the circle with radius r is: A=πr2,where,r=8 inches given. So, A=π(8)2=64π square inches.

What is a circle diameter?

Diameter of a circle

The diameter is the length of the line through the center that touches two points on the edge of the circle.

What is the radius of 8cm?

= 50.29 (approx.)

What is the circumference of 6cm?

12π cm
Finding the Circumference:

If r = 6 cm, the the circumference is c = 2π(6) = 12π cm, if writing in terms of π. If you prefer a numerical value, the answer rounded to the nearest tenth is 37.7 cm.

What is the radius of a 20cm circle?

You see the radius is 1/2 the diameter and 1/6 the size of circumference.

Look at the table.

What is the radius of a circle whose diameter is given as 24cm?

∴ The radius of a circle of diameter 24 cm is 12 cm.

What is the radius of a 14 foot circle?

Since we know that the radius is half the diameter of a circle, we know that the radius of the given circle is 142=7ft .

What is the radius of a circle with 12 cm?

So, if d=12 cm, r=12(12)=122=6 cm.

What is the diameter of 24 cm radius?

24=2r. r=24/2=12cm.
