Question

A stainless steel patio heater is a square pyramid. The length of one side of the base is 19.6 m. The slant height of the pyramid is 90.9 in. What is the height of the pyramid?

Answer 1

Answer:

90.8 m

Step-by-step explanation:

Pythagorean Theorem

A²+B²=C²

slant height = C

A = 19.6/2=9.8m

90.9 in to m = 2.3m

9.8²+B²=2.3²

B²=90.9²-2.3² = 8257.52

B=$\sqrt{8257.52}$ = 90.8
