What is the area of a 10 in diameter circle?

What is the area of a 10 in diameter circle?

=78.5 square inches.

How big a circle is 10 cm?

Answer. We know that C = πd. Since the diameter is 10cm, we know that C = π x 10cm = 31.42cm (to 2 decimal places).

How do you draw a 10 cm diameter circle?

Step-by-step explanation:

1. Mark a point X on the centre of your page.
2. To draw a circle of diameter 10 cm, we need to first calculate the radius.
3. Radius = diametre/2 = 10/2 = 5 cm.
4. Now, take a compass and open it to 5 cm.
5. Place the needle of the compass on the point marked X and draw a full circle on the page.

What is the circumference with a radius of 10?

The circumference of the circle is 20π cm or about 62.8 cm.

What is the diameter of 10 centimeters?

Or to put it another way, the circumference is approximately 3 times bigger than the diameter. Look at the table below and see if you can spot the pattern….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

How do you find the diameter of 10 cm?

Answer: Diameter is the longest line that you can draw in a circle passing through the centre of the circle. Radius is the line joining the centre of the circle to any point on the circumference. Answer: the radius of 10 cm diameter circle is 5 cm.

What is the diameter of 10 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

How do you find the diameter of a circle with 12 cm?

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.

How do you draw a circle with diameter of 12 cm?

What is the circumference of 7 cm?

∴ , the circumference is approximately 43.98 cm .

How do I figure out circumference?

The circumference is the distance around a circle. In other words, it’s the perimeter of the circle. And we find the circumference by using the formula C = 2πr.

How to find the area of a circle using diameter?

Area of a circle = π * r 2. Area of a circle diameter. The diameter of a circle calculator uses the following equation: Area of a circle = π * (d/2) 2. Where: π is approximately equal to 3.14. It doesn’t matter whether you want to find the area of a circle using diameter or radius – you’ll need to use this constant in almost every case.

Where does the radius of a circle begin and end?

The radius begins at the center of the figure and ends at the figure’s margin. You can find diameter of a circle by multiplying the radius of a circle by two: Diameter = 2 * Radius

What is the difference between diameter and radius in math?

💡 The diameter is the line that crosses the center of the figure and touches both of its margins. The radius begins at the center of the figure and ends at the figure’s margin. You can find diameter of a circle by multiplying the radius of a circle by two: Diameter = 2 * Radius

What is a sector of a circle?

>A sector of a circle is section of a circle between two radii. You can think of it as a giant slice of pizza. >It’s a “cut-off” part of a circle, limited by a chord or a secant.
