lengakapi tabel berikut beserta cara nya ya

Volume kerucut = 1/3 × phi × radius kuadrat × tinggi kerucut
radius = 1/2 diameter
diameter = 2 × radius

a.) r=3,5
d=2×3,5=7
V=1/3×22/7×3,5×3,5×5=1/3×22×5=36,67
b.) r=1/2×14=7
d=14
V=1/3×22/7×7×7×10=1/3×22×70=1/3×154=51,33
c.) r=0,14m=14cm
d=2×0,14=0,28m=28m
V=1/3×22/7×14×14×t
12320= 1/3×44×14×t
12320=205,33×t
12320/205,33=t
0,016=t

menurut perhitungan sy gt, maaf kalo salah
