the formula for the circumference of a circle is pi*diameter.
the diameter is 2*radius
so if 1.5 is the radius, 3 is the diameter
plug 3 into the formula...
circumference=3.14*3
circumference=9.42

What is the radius of a circle whose diameter is 15 meters?
The radius of a circle is 1/2 of its diameter. If the diameter is 15 meters, then the radius is 7.5 meters.
What is the equation to get the area of a circle if you have the radius?
The area of a circle is given by: pi multiplied by the square of the radius. So if the radius is 15, the area is 225pi (225 is 15 squared)
What is the radius of the circle that has diameter of 30 feet?
The radius is 15 feet 2r=30 30/2=15 15 is the radius
What is the area of a circle if the radius is 15?
The area of a circle has the formula πr2 This means pi x radius squared. If the radius is 15. Square 15- 15x15. Multiply it by pi(3.14159265) Answer is 706.9mm2
What is the radius of a circle if the circumference is 8cm?
The radius is 1.27cm
What is the radius of a circle with a diameter of 15 cm?
The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm
Area of circle 15 cm radius?
The area of a circle with a radius of 15 cm is: 706.9 cm2
What is the area of a circle when the radius is 15?
Area of a circle= (22/7)*r^2 where, r is the radius of the circle when r=15, area of the circle= 3.14*15*15 = 706.5 sq.units
What is the radius of a circle with a circumference of 15?
Radius is 2.39
What is the circumference of a circle with a radius of 15?
Radius is 2.39
If the diameter of the circle is 30 mm then what is the radius of the circle?
The radius if the circle is half of its diameter and so 30/2 = 15 mm
