What is the diameter and area of R 5cm?
Answer: The area of the circle with a radius of 5 cm is 78.5 cm2.
What is the circumference of diameter of 5 cm?
Circles (basic)
| Diameter | Circumference | Approx. |
|---|---|---|
| 10 cm | 31.4 cm | 10cm X 3 = 30 |
| 2 cm | 6.24 cm | 2cm X 3 = 6 |
| 5 cm | 15.7 cm | 5cm X 3 = 15 cm |
What is the circumference if radius is 5cm?
Explanation: The formula for the circumference of a circle is 2πr so all we have to do is plug in 5 for our radius: 2π(5) which can be simplified to 10π .
What is the area of 5cm diameter?
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 diameter of a 6 cm circumference circle?
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. Suppose you only know the diameter?
What is the diameter of a 7cm circle?
Here,diameter is 7 cm. So radius is 7/2=3.5 cm.
Would a circle with a radius of 5 cm have the same circumference as a circle with a diameter of 10 cm?
Would a circle with a radius of 5 cm have the same circumference as a circle with a diameter of 10 cm? A. No, because diameter has a different value with radius.
What is the circumference in inches of a circle with radius of 5 inches Use 3.14 for π?
Use 3.14 for n. C = [?] inches.
Which is the area of a circle with a radius of 6 cm?
What is the area of a circle with radius 6 centimeters?
| Result: The area of a circle with radius 6 is 113.1 | |

| r = 6 d = 12 C = 37.7 | A = πr2 = π(d2)2 A = C24π π = 3.1415 A = area C = circumference or perimeter r = radius, d = diameter |
How big is a 5 centimeter circle in area?
What is the area of a circle with a DIAMETER of 5 cm (radius of 2.5 cm)? How big is a 5 centimeter circle? The area of a circle is pi times the square of its radius. The radius is half the diameter. The diameter of a circle is the distance from one edge to the other, passing through the center.
How to calculate the diameter of a circle?
The formula used to calculate circle diameter is: ø = 2 · r. Symbols. ø = Circle diameter; r = Circle radius; Radius of Circle. Enter the radius of a circle. The radius is the distance between the centre and any point on the outer edge of a circle. Diameter of Circle. This is the diameter of a circle that corresponds to the specified radius.
What are the three dimensions of a circle?
There are three dimensions most often used to describe a circle: 1 The diameter – defined above 2 The radius – the distance from the circle’s center or origin to the edge, one half the diameter 3 The circumference – the length of the outside boundaries of the circle More …
Which is the correct formula for the radius of a circle?
Radius of a circle = Diameter/2. Or. Diameter of a circle = 2 x Radius. Let us discuss a few important theorems and their proofs related to the chord of a circle.
