Step-by-step Step-by-step explanation:
r=d/2=14/2=7yd
From hyp²=opp²+adj²
opp²=hyp²-adj²
h²=25²-7²
h²=625-49
h²=576
square root of both sides
√h²=√576
h=24yd
Volume of a cone=1/3pir²h
V=1/3×22/7×7²×24
V=22×7×8
V=1232yd²
Volume of pyramid=1/3AH
hyp²=opp²+adj²
14²=h²+5²
196=h²+25
h²=196-26
h²=171
√h²=√171
h=13.1yd
V=1/3×B×H×H
V=1/3×
