An igloo can be modeled as a hemisphere. Its radius measures \( 4.5 m \) . Find its volume in cubic meters. Round your answer to the nearest tenth if necessary. Answer: 

Stabilisci se le seguenti quaterne di numeri rappresentano le misure in centimetri delle lunghezze dei lati di un quadrilatero. Se si, calcola it perimetro del quadrilatero. a \( 13,24,7,41 \) b \( 3,10,8,22 \) e \( 11,9,9,15 \)

296. Il lato, l'altezza e una diagonale di un rombo misurano, rispettivamente, \( 35 \mathrm{~cm}, 33,6 \mathrm{~cm} \) e 56 cm . Calcola la misura dell'altra diagonale.

A sector has central angle \( \frac{5}{7} \pi \) and radius 18 . Find the area of the sector. Give your answer in terms of \( \pi \) or as a decimal rounded to two decimal places.

Dalle diagonali all'altezza Un rombo ha le diagonali che misurano 24 cm e 7 cm e il lato di \( 12,5 \mathrm{~cm} \). Calcola l'altezza del rombo.

AFerris wheel has a radius r of 24.5 feet. The height of the tower \( t \) is 30.8 feet. The horizontal distance d from the origin to the base of the tower which lies to the right of the origin is 43.7 feet. Find the standard form of the equation of the circle represented by the Ferris wheel. The standard form of the equation of the circle represented by the Ferris wheel is (Do not type units. Type any numbers as decimals. Use the variables \( x \) and \( y \).
