You blow a bubble in the shape of a sphere. it has a radius of 5 inches. which choice is closest to its surface area? use 3.14 to approximate pi.
79
314
523
1256

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
