Q. What is the circumference of a 4 cm diameter circle?
Since the diameter is known to us, we can calculate the radius of the circle. Therefore, Circumference of the circle is 4π cm.
Q. What is the radius of 12cm?
So, if d=12 cm, r=12(12)=122=6 cm.
Q. What is the radius of 20m?
The diameter of a circle is the distance from one edge to the other, passing through the center. It is twice the radius….Diameter of a Circle.
| Diameter | m2 | ft2 |
|---|---|---|
| 20.0 m | 314.2 | 3,382 |
| 20.1 m | 317.3 | 3,415 |
| 20.2 m | 320.5 | 3,450 |
| 20.3 m | 323.7 | 3,484 |
Q. What is the area of 2.8 cm?
A circle of radius = 1.4 or diameter = 2.8 or circumference = 8.796 cm has an area of: 6.158 × 10-10 square kilometers (km²) 0.0006158 square meters (m²)
Q. What is the area of a 50 cm circle?
304.266 square inches (in²)
Q. What is the radius of the field?
The radius of a field in the form of a sector is 21m. The cost of constructing a wall around the field is Rs. 1500 at the rate of Rs. 20 per meter.
Q. What is the circumference of a tree called?
Girth is a measurement of the distance around the trunk of a tree measured perpendicular to the axis of the trunk. Use of girth to arrive at an equivalent diameter is an older forestry measurement that is still used. In the United States girth is measured at a height of 4.5 feet above ground level.
