Area = pi*(diameter/2)2 = pi*(2/2)2 = pi So pi sq metres = 3.14159 sq metres (to 5 dp)
Circumference is equal to 2 times pi times the radius. The radius is half the diameter, so pi times the diameter is also the circumference. In this case, the diameter is 3 meters so 3 times pi equals 9.42 So the circumference is about 9.42 meters.
Its 2 meters
2000 meters.
Area of a circle = pi R2If 'R' (the radius) is 1 meter, thenArea = pi (1)2 = pi = 3.142 square meters (rounded)
Area = pi*(diameter/2)2 = pi*(2/2)2 = pi So pi sq metres = 3.14159 sq metres (to 5 dp)
Circumference is equal to 2 times pi times the radius. The radius is half the diameter, so pi times the diameter is also the circumference. In this case, the diameter is 3 meters so 3 times pi equals 9.42 So the circumference is about 9.42 meters.
circumference equals: pi x 2 x radius So, 424 x 2= 848 848 x 3.14 (pi)= 2662.72 meters is the circumference
Its 2 meters
2000 meters.
2 centimeters is equal to 0.02 meters.
The volume of a cylinder equals the area of the base times the height, which equals pi x radius squared x height. Inserting the numbers, V = pi x (2 m.) squared x 5 m. = pi x 4 m. squared x 5 m. = 20 x pi meters cubed or 20 x pi cubic meters.
Area of a circle = pi R2If 'R' (the radius) is 1 meter, thenArea = pi (1)2 = pi = 3.142 square meters (rounded)
2,000 meters = 2 kilometers
multiply by 1000 2000 meters
2 meters and 10 centimeters
Circumference of wheel = 2*pi*1 = 2*pi 50/2*pi = 7.957747155 nearly 8 meters
