Question

find the nearest mm the radius of s sphere whose surface area is equal to the whole surface area of a cylindrical of height 16cm and diameter 4cm

pls answer this​

Answer 1

There are five basic equations which completely describe the cylinder with given radius r and height h :

1. Volume of a cylinder: V = π * r² * h ,
2. Base surface area of a cylinder: A_b = 2 * π * r² ,
3. Lateral surface area of a cylinder: A_l = 2 * π * r * h ,
4. Total surface area of a cylinder: A = A_b + A_l ,

Answer 2

Answer:

Divide the area (in square units) by Pi (approximately 3.14159). Example: 303,000/3.14159 = 96447.98.

Step-by-step explanation:

Take the square root of the result (Example: 310.56). This is the radius.

Now double the radius to get the diameter (Example: 621.12 meters)
