v=1/3 t* r*r*r* h
a. if v=25,t=3 and r=5,find the value of h.
25 = (1/3)(3)(5^3) h
25 = 125h
h = 25/125 = 1/5
b. if v=96,r=4 and h=6, find the value of t.
96 = (1/3)(4^3)(6) t
96 = 128t
t = 96/128 = 3/4

a) 25=1/3*(3*5*5*5*h)
75=375h
h=1/5
b) 96=1/3*(t*4*4*4*6)
32=384t
t=1/12

我b計錯左b) 96=1/3*(t*4*4*4*6) 288=384t t=3/4
75=375h
h=1/5
b) 96=1/3*(t*4*4*4*6)
32=384t
t=1/12
