A sphere has a radius of 16 in. Which statements about the sphere are true? Select two A. The sphere has a diameter of 8 in.
The sphere has a diameter of 32 in.
B. The surface area of the sphere is 512s in..
C. The surface area of the sphere is 1,024 s in.
D. The surface area of the sphere is 4,096 x in?.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
