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

Answer 1

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)
