What is the diameter of a circle with a 4 radius?
If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm.
What is the radius of a circle with 4cm?
the radius is 0.6366 cm.
What will be 4 times the diameter of a circle if the radius of the circle is 2cm?
the diameter of circle will be 4 cm.
What is the radius of 5cm?
r = 0796 is right answer.
What is the area of 5cm?
78.55cm
R2 (radius squared) means radius × radius. Therefore a circle with a radius of 5cm has an area of: 3.142 × 5 × 5 = 78.55cm2.
What is the circumference of a 4cm circle?
The formula for the circumference of a circle is C = 2πr or C= πd where r represents length of r and d represent length of diameter. The length of a diameter is 2r which is why C= πd. Using this formula, we know that r= 4cm. Thus, C= 2(4)π = 8π ≈ 25.13 centimeters.
How do you find the inner diameter from the outside diameter?
Hi Karla, to find the inner pipe diameter, you need to subtract 2 times the wall thickness, 3/16, from the outside diameter of 2.
How do you draw a circle with a radius of 4cm?
Draw a line segment 4 cm.
- ii. Take a point P outside the circle and draw a secant PAB, intersecting the circle at A and B.
- iii. Produce AP to C such that AP = CP.
- iv. Draw a semi-circle with CB as diameter.
- v. Draw PD perpendicular to CB, intersecting the semi-circle at D.

What is pi value?
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. In decimal form, the value of pi is approximately 3.14.
Are all radii of a circle equal?
By definition, all radii of a circle are congruent, since all the points on a circle are the same distance from the center, and the radii of a circle have one endpoint on the circle and one at the center. The length of the diameter is twice that of the radius. Therefore, all diameters of a circle are congruent, too.
What is the area of 7cm?
The area of a square is A = s², where s is the length of one of the 4 congruent sides of the square. A = 49 cm² is the area of a square of side 7 cm in length.
What is the area of a circle if the radius is 4cm?
If the radius of a circle is 4cm, what is the area? π is a button on your calculator you can find, but is also generally known as 3.14, you can use either one, but teachers usually prefer you use the π button.
What is the diameter of a circle with a radius of 2?
A circle of radius = 2 or diameter = 4 or circumference = 12.57 cm has an area of: 1.257 × 10 -9 square kilometers (km²) 0.001257 square meters (m²) 12.57 square centimeters (cm²)
What is the distance from the center of a circle?
The distance from the center of a circle to any point on the circle is called the radius of this circle.A radius of a circle must be a positive real number. The circle with a center O O and a radius r r is denoted by c(O,r) c ( O, r).
What are the three dimensions of a circle?
There are three dimensions most often used to describe a circle: The radius – the distance from the circle’s center or origin to the edge, one half the diameter The circumference – the length of the outside boundaries of the circle Starting from the diameter, you can easily find the other two.
