To find the surface area of a spear, we need to know the radius of the sphere. However, you have only provided the "demeanor" of the sphere, which is not a standard measurement. It is possible that you meant to provide either the diameter or the circumference of the sphere.
If the "demeanor" you mentioned actually refers to the diameter of the sphere, we can find the radius by dividing the diameter by 2. So if the diameter is 40 inches, the radius would be 40/2 = 20 inches.
The surface area of a sphere can be calculated using the formula:
Surface Area = 4πr²
Substituting the radius (r = 20 inches) into the formula, we get:
Surface Area = 4π(20)²
Surface Area = 4π(400)
Surface Area = 1600π
Therefore, the surface area of the sphere would be 1600π square inches.
