Two spheres of the same density have a ratio of 9 to 16 in surface area. if the small sphere weighs 15 kg, what does the large sphere weigh?

109 trust me

step-by-step explanation:

Surface area of a sphere = 4 pi r^2

radius of small sphere = sqrt (9/4pi) = 0.8463

radius of larger one = sqrt (16/4pi) = 1.1284

ratio of the weights is 1.1284^3 : 0.8463^3 = 2.37

large sphere weighs 15 * 2.37 = 35.55 kg

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
