What is the area of the diameter is 12?

What is the area of the diameter is 12?

≈113 . First you need to find the radius, the key term to find the radius is diameter=2⋅radius ; therefore the radius r is 122=6 inches. To find the area of a circle, you need to use the formula A=π⋅r2 ; therefore the area A is π⋅62≈113 square inches.

What is the area of the diameter is 1.8 m?

Step-by-step explanation: In terms of diameter: Area = π . (d/2)2 = 3.14 × (1.8/2)2 = 3.14 × (0.9)2 = 2.55 square m.

What is the diameter of a 5 circle?

Circumferences and areas of circles with diameters in inches.

What is the circumference of a 1 diameter circle?

3.14
Multiply the diameter by π, or 3.14. The result is the circle’s circumference.

What is the circumference of a 1 Metre diameter circle?

To calculate the circumference of a circle with a radius of 1 meter, simply follow these steps: Multiply the radius by 2 to get the diameter of 2 meters. Multiply the result by π, or 3.14 for an estimation. And there you go; the circumference of a circle with a radius of 1 meter is 6.28 meters.

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.

What is the diameter of a 2 ft 2 cm circle?

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
