A sphere with a diameter of 5 feet long is being painted. how much more paint would be needed to paint a sphere that has four ti
MArishka [77]

well, if the diameter is 5, thus its radius must be half that, or 2.5, and therefore, the radius of the one four times as much will be (4)(2.5).

Let's simply get their difference, since that'd be how much more is needed from the smaller to larger sphere.

~\hfill \stackrel{\textit{surface area of a sphere}}{SA=4\pi r^2}\qquad \qquad r=radius~\hfill \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{\large difference of their areas}}{\stackrel{\textit{radius of (4)(2.5)}}{4\pi (4)(2.5)^2}~~ - ~~\stackrel{\textit{radius of 2.5}}{4\pi (2.5)^2}}\implies 100\pi -25\pi \implies 75\pi ~~ \approx ~~235.62~ft^2

Given the figure below, find the value of x and z.
melomori [17]

Answer:

X=12 and z=109

Step-by-step explanation:

z has the same degree measure as the Angle across from it of 109 degrees.

to solve for x we first have to subtract 109 from 180 since it’s a straight angle to get 71. then we solve for the equation 8x-25 = 71, adding 25 to both sides, 8x=96, dividing 8 by both sides, to get x=12
