Step-by-step explanation:
Answer:
60%
Step-by-step explanation:
15/25 = x/100
0.60 = x/100
0.60 * 100 = x
60 = x
25 * 60% = 15

Answer:
- 326.6 square inches
- 3402 square feet
Step-by-step explanation:
The net will be a rectangle representing the lateral area. Its length will be 2π(4 in), the circumference of the box, and its height will be 9 in, the height of the box. On either side of that rectangle will be an 8-in diameter circle representing the ends of the box.
The total surface area is given by the formula ...
SA = 2πr(r +h)
For one box, the area is ...
SA = 2(3.14)(4 in)(4 in +9 in) ≈ 326.6 in² . . . . area of one box
__
There are 144 square inches in a square foot, so the area required for 1500 boxes is ...
(1500)(326.56 in²)/(144 in²/ft²) ≈ 3402 ft² . . . area of 1500 boxes
Part A: Find the area of the circle of spilled milk as a function of time, or A[r(t)].
A(r(t)) = A(4t) = π(4t)^2 = 16πt^2
A[r(t)] = 16πt^2
Part B: How large is the area of spilled milk after 4 minutes? You may use 3.14 to approximate π in this problem.
After 4 minutes, A = 16(3.14)(4)^2 = 803.84 cubic meters.
