Answer:
7.85 km/h
Step-by-step explanation:
Answer:
3,052.08 cm^3
Step-by-step explanation:
Here, we want to find the volume of the sphere
We have the formula as;
V = 4/3 * pi * r^3
The radius is 9 cm
V = 4/3 * 3.14 * 9^3
V = 3,052.08 cm^3
Answer:
Radius is a line segment between the center and a point on the circle or sphere.
Step-by-step explanation:
We define radius of a circle as:
- A chord has both endpoints on the circle
- Radius is defined as the line segment that passes through any point on the circle to the center of circle.
- All the points on the circle are equidistant from the center of the circle.
- A line segment between the center and a point on the circle or sphere.
- The word radius describes the length of this line segment.
- Radius is the length of straight line from the center of circle to the circumference of circle.
- Thus, we can write
Radius is a line segment between the center and a point on the circle or sphere.
