The answer to the question is the first, third and fifth
Answer:
5229 mm³
Step-by-step explanation:
Volume of square pyramid

b = base length = 25 mm
H = height
We have to find 'H' using Pythagorean theorem,
slant height (hypotenuse) = 28 mm
leg₁ = base length ÷ 2 = 25÷2 = 12.5
leg₂ = H
H² + (12.5)² = 28²
H² = 784 - 156.25
= 627.75

H = 25.01 mm

= 5229 mm³

Answer:
530
Step-by-step explanation:
200+6(55)
6x55=330
200+330=530
I believe it’s pie times radius squared so 6ft = 3.14•3 squares and 8ft = 3.14•4 squares and then subtract
