The volume of a spear is 998 cubed what is the approximate radius of the spear use the formula V equals 4/3 and 3.144 pi
Using the formula for the volume of a sphere:
V = (4/3) * π * r^3
where V = 998 and π = 3.144, we can solve for the radius (r):
998 = (4/3) * 3.144 * r^3
998 = 4.192 * r^3
r^3 = 998 / 4.192
r^3 ≈ 238.217
Taking the cube root of both sides to solve for r:
r ≈ ∛238.217
r ≈ 6.95 (approximate radius of the sphere)
