Geometry question

Answer 1

A spherical pear of radius 4 cm is to be divided into 8 equal parts by cutting it in halves along the same axis .Find the surface area of each of the final piece

Answer 2

\(a.)20\pi\\
b.)24\pi\\
c.)25\pi\\
d.)19\pi\)

Answer 3

what is the formula for the surface area of a sphere?

Answer 4

\(A_s=4\pi r^2\)

Answer 5

so we can find the area of the curved part of each piece. (1/8 of the sphere's)

Answer 6

oh yes

Answer 7

what do you get for the "curved part" ?

Answer 8

\(8\pi\) ?

Answer 9

yes. now for the other surfaces
