Find the density of a soda can with a radius of 3.25 cm, a height of 122 cm, and a mass of 40 g.
dimaraw [331]

Answer:

density = 9.88*10^{-3} g/cm^3

Step-by-step explanation:

Step 1: Volume of soda can

volume = \pi r ^{2}  h

=> \pi 3.25^{2}*122

volume = 4048.3cm^{3}

Step 2: Using answer from step 1 to calculate density

density=\frac{mass}{volume}

density = \frac{40}{\pi 3.25^{2}*122  }

density = 9.88*10^{-3} g/cm^3

The sides of AFGH are FG = 6x+7, GH = 8x - 5, and FH = 10x - 11. If the perimeter of FGH is 87, list the angles
liraira [26]

Answer:

<em>∠ H, ∠G, ∠F </em>

Step-by-step explanation:

6x + 7 + 8x - 5 + 10x - 11 = 87

24x = 96

x = 96 / 24 = 4

FG = 6(4) + 7 = 31 units

GH = 8(4) - 5 = 27 units

FH = 10(4) - 11 = 29 units

FG is the longest side ⇒ ∠H is the largest angle.

GH is the shortest side ⇒ ∠F is the smallest angle

<em>∠ H, ∠G, ∠F</em>
