What is the area of diameter 12 m?
= 113.04 square meter or 113.04 m^2.
What is the area of 12 diameter?
≈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 circumference of 12 meters?
Or, approximately: C=75.398 m rounded to the nearest thousandth.
What is the area of a 12 in square?
12² = 144. Extending that, if you say “12 inches squared,” it’s a logical process to square 12 inches, giving us 144 inches.
What is the diameter of 12cm?
So, if d=12 cm, r=12(12)=122=6 cm.
How big is a 12 meter circle in area?
How big is a 12 meter circle? Area of a Circle Formula The area of a circle is pi times the square of its radius. The radius is half the diameter.
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 radius of a circle with diameter 12?
A circle of radius = 6 or diameter = 12 or circumference = 37.7 m has an area of: 0.0001131 square kilometers (km²) 113.1 square meters (m²) 1.131 × 10 6 square centimeters (cm²)
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
