    the diameter of the first one is 5 the diameter of the third sphere is 3/4 the diameter of the first one

    your question states: The sphere below has a radius of 2.5 inches and an approximate volume of 65.42 cubic inches A second sphere has twice the radius of the given sphere. A third sphere has a diameter that is three-fourths of the diameter of the given sphere

    the diameter of the given is 5 so multiply 5*0.75 = 3.75

    to find the radius, divide the diameter by 2 3.75/2
