Step-by-step explanation:
1.The formula in finding the area of a circle is derived from the area of a parallelogram. It is false.
2. The area of a circle is πr² where r is the radius of the circle. It is true.
3. The area of a circle is equal to pi divided by the square of the radius. It is false.
4. The diameter of a circle is equal to twice its radius i.e. d = 2r. It is true.
5. If r = 2.1 m
Area of circle, A = πr²
= 3.14 (2.1)²
= 13.85 m²
Henc,e this is the required solution.
The variable we need to isolate is P. In order to do so, we add a / 3w on both sides.
P =

Answer:
V ≈ 2,048 ft^3
<u>Hope this helps :)</u>
Step-by-step explanation:
The symbol ^ means raised to a power.
Formula for Volume of Sphere - V = 4/3 π r^3
1. To find the volume of a sphere, first find the radius with the given diameter 16.
16 ÷ 2 = 8
Radius = 8
2. Substitute r for 8 and solve, and 3 will be used for π.
V ≈ 4/3 • 3 • 8^3
V ≈ 4/3 • 3 • 512
V ≈ 4/3 • 1536
V ≈ 6144/3
V ≈ 2,048
