What is the area of a cirle if diameter is 16?
Area of a circle is pi r^2 diameter is twice the radius. 3.14*8*8=64*pi or approximately 200.96
What is the area of a circle with the radius of 5?
A circle with a radius of 5 units has an area of 78.54 square units.
Area of circle with radius of 5?
A=pi times R squared If the radius is 5, the area is 25pi
What is the area of 5 km radius in square km?
An area of 5km radius implies a circle. The area of a circle of radius r is {pi}r2. Area ~= 3.14 x 5 x 5 km2 ~= 78.54 km2.
The area of a circle of radius 10 units is equal to the surface area of a sphere of radius 5 units?
true
The radius of a cirle is what percent of the diameter?
the radius of a cirle is what percent of the diameter
What is the area of a circle with a diamiter of 46?
The area of a cirle is: PI * r2 Where "r" is the radius, and PI is approximately 3.14. Hint: A radius is half of the diameter.
What is the area of a cirle with a radius of 12 ft?
The formula is pi (3.14) x radius x radius 3.14 x 12 x 12 = 446.4
Is the radius of a cirle half of the diameter?
Yes.
What is the area of a circle with radius 2?
To find the area of a cirle you multiple pi (3.14) by the radius squared, so you would have to find 3.14 times 4, which is 15.7.
The formula for circumference of a cirle is?
pi*radius squared
What is the area of a cirle if diameter is 16?
Area of a circle is pi r^2 diameter is twice the radius. 3.14*8*8=64*pi or approximately 200.96
Which of these is a radius in a cirle?
The line from the centre of the circle to any point on its circumference
What is the formula for the circumference of the cirle?
circumference of a circle = 2*pi*radius or pi*diameter
Area of a cirle with a circumference 66cm?
The area is 346.639 cm2
What is the area of a circle with the radius of 5?
A circle with a radius of 5 units has an area of 78.54 square units.
You can see a grey circle with a little white cirle in it with a radius of 3 What is the radius of the diagram's larger circle if the area of the shaded region is 72 pie?
Area of a circle with radius r = pir2Area of the largest circle = Area of the smallest circle + Area of the shaded regionSince areas of the smallest circle and the shaded region are 9pi and 72pi, the Area, A, of the largest circle isA = 9pi + 72pi = 81pi, where r2 = 81.Thus, the radius of the largest circle is 9
