Glass A measures 84 mm in diameter and 175 mm tall. Glass B measures 96 mm in diameter and 125 mm tall. Which glass holds more l

FrozenT [24]

Answer:

Glass A

Step-by-step explanation:

Volume = п r ² h

п = 3.14 aprox.

r = radius = diameter/2

h = tall

glass A

volume = 3.14 * (84/2)² * 175

volume = 3.14 * 42² * 175

volume = 3.14 * 1764 * 175

volume = 969318mm³

glass B

volume = 3.14 * (96/2)² * 125

volume = 3.14* 48² * 125

volume = 3.14 * 2304 * 125

volume = 904320mm³

Answer:

969318 > 904320

then:

Glass A holds more liquid

Perform the indicated operations. Write the answer in standard form, a+bi.<br> -4 + 4i / -3-6i

vesna_86 [32]

Answer:

$\frac{ - 4 + 4i}{ - 3 - 6i} \\ \frac{ - 4 + 4i}{ - 3 - 6i} \times \frac{ - 3 + 6i}{ - 3 + 6i} \\ = \frac{12 - 24i - 12i + 24 {i}^{2} }{ {( - 3)}^{2} - {(6i)}^{2} } \\ = \frac{ - 12 - 36i}{45} \\ = \frac{ - 12}{45} \frac{ - 36i}{45} \\ than \: you$
