Which statement about the amount of paint found by
Sheila is true?
A piece of solid, spherical glass has a circumference of
37.68 cm. The sphere is cut in half, creating two
identical hemispheres. Using 3.14 for 7, Sheila
computes the amount of paint needed to cover the
hemishpheres.
O Sheila found the minimum amount of paint needed
to cover the curved surface of one of the
hemispheres.
C = 2 mm
37.68
O Sheila found the minimum amount of paint needed
to cover the bases of both hemispheres.
2(3.14)r
r = 6 cm
O
Sheila found the minimum amount of paint needed
to cover both hemispheres.
O Sheila found the minimum amount of paint needed
SA = (4 m²) + m²
to cover the entire surface of one of the
hemispheres.
SA ==
2 m(6)² + (6)²
SA 72(3.14) + 36(3.14)
