Answer:
$0.30
Step-by-step explanation:
3.68*.0825= .3036
To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above:
- The<span> rectangular deck has the following dimensions: 12 ft by 14 ft.
- When the length and width are increased by the same amount, the area becomes 288 ft</span>².
2. Therefore, you have:
A=bxh
288=(12x)(14x)
288=168x²
3. When you clear the x, you obtain:
x=√288/168
x=(2√21)/7≈1.31
1.) A = πr^2
Rate of change (dA/dr) = 2πr.
When r = 3, dA/dr = 2(3)π = 6π ft^2/ft
2.) V = πr^2h
Rate of change of volume given constant r is dV/dt = πr^2dh/dt = π(6)^2(3) = 108π cm^3/min
