Answer:

1) Volume = ⅓×pi×r²×h

= ⅓×3.14×7²×14

= 718.01 in³

2) ⅓×3.14×5²×10

= 261.67 cm³

3) r = 12÷2 = 6

Volume = (4/3)×3.14×6³

= 904.32 mi³

4) 3.142×4²×5

= 251.2 ft³

5) radius = 2

(4/3)×3.14×2³ = 33.49 ft³

6) radius = 2

3.142×2²×3 = 37.68 m³

The answer is 13, i got this by using the pythagorean theorem. a^2 + b^2 = c^2. in this case it would be 84^2 + b^2 = 85^2. then that would turn into 7056 + b^2 = 7225, subtract both sides by 7056 to get b^2 = 169, then square 169 to get 13 :)

Can anyone help me solve this?

Alecsey [184]

Answer:

Step-by-step explanation:

$(\sqrt{z} +\sqrt{22})(\sqrt{z} -\sqrt{22})=35$

Subtract both sides from 35

$(\sqrt{z}+\sqrt{22} (\sqrt{z} -\sqrt{22})-35=35-35$

Simplify:

$(\sqrt{z})^{2} -57=0$

Factor $(\sqrt{z})^{2} -57: (\sqrt{z}+\sqrt{57}) (\sqrt{z}-\sqrt{57})$ =0

$\sqrt{z} +\sqrt{57}=0 or \sqrt{z} -\sqrt{57}=0$

$\sqrt{z} +\sqrt{57} =0: No Solution for Z$

$\sqrt{z} -\sqrt{57} =0: z=57$

Your answer will be z=57

and No solution
