What is a 6 inch radius?

What is the area of a 6 inch radius?

Answer: The area of a circle with a diameter of 6 units is 28.27 sq. units or 9π square units.

What is the radius of a 6 inch circumference?

Circumference & Areas

How do you measure a 6 inch circle?

Rewriting the equation, the circumference = 3.14 X diameter. For example, a circle with a diameter of 6 inches has an approximate circumference of 18.84 inches. If you only know the radius of the circle, the formula “2 times pi times the radius” can be used.

How big is a circle with a radius of 6?

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.

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).

What is the area of 6cm?

Answer: The area of the square with sides of length 6 cm is 36 cm2.

What is the radius if the diameter is 6cm?

So, if r(Radius) = 6 cm, then d(Diameter) = 12 cm as 6cm*2 = 12cm… HOPE MY ANSWER HELPED!!!

How do you measure 6 cm diameter?

Answer

1. Take your Rounder.
2. Insert your pencil.
3. measure 3cm in the rounder.
4. place the pointed end on the paper and draw the circle.
5. The circle drawn will be with diameter of 6 cm.

What is the area when 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 the radius of 9cm?

The answer is 9.42 cm.

What’s the area of the radius is 5?

Summary: The area of a circle with a radius of 5 is 25π sq.

What is the area of a 10 circle?

=78.5 square inches.

What is the area of a 5 inch circle?

1 Answer. Alan P. =25π or approximately 78.54 square inches.

What is the radius of 8cm?

= 50.29 (approx.)

What is the radius of 15cm?

Hence, radius of circle is 7.2 cm.

What is the radius of a circle 12 cm?

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

How do you draw a 12cm circle?

Steps Of Construction:

1. i) Draw a line segment AB = 12 cm.
2. ii) Draw a circle with centre O and AB as diameter.
3. iii) From O, take a point P such that OP = 10 cm.
4. iv) Bisect OP and draw another circle with OP as diameter which intersects the given circle at T and S.
5. v) Join TP and SP.
6. TP and SP are the required tangents.

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 circle pie?

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).

Who invented 0?

About 773 AD the mathematician Mohammed ibn-Musa al-Khowarizmi was the first to work on equations that were equal to zero (now known as algebra), though he called it ‘sifr’. By the ninth century the zero was part of the Arabic numeral system in a similar shape to the present day oval we now use.

Do mathematicians believe in God?

Mathematicians believe in God at a rate two and a half times that of biologists, a survey of members of the National Academy of Sciences a decade ago revealed. Admittedly, this rate is not very high in absolute terms.
