I think the first one is correct. Since “three less than z squared” insinuate that the value is 3 units less than the value z^2
Answer:
104.8cm³(1 decimal place)
Step-by-step explanation:
Volume of a cone is given by the formula
V=1/3πr²h
we are given a radius of 5 and a height of 4 so we will just substitute for the values and we will give our pie as 22/7
V=1/3× 22/7×5²×4
V=1/3 × 22/7 ×25 ×4
V=2200/21
V=104.76190476
V=104.8cm³(1decimal place)

12 inches in 1 foot
12*12*12 cubic inches in 1 cubic foot = 1728 in^2
So 7125 in^3 = 7125/1728 = 4.123 ft^3 to nearest thousandth
