Answer:

6 + 3\sqrt{10\\} or 6 - 3\sqrt{10\\}

The sphere shown has a diameter of 24 inches. Which choice is closest to its surface area? Use 3.14 to approximate pi.
tamaranim1 [39]
I don't know what your choices are, but I did the questions for you.
R=D/2, R=12, R=radius,
SA= 4 times 3.14 12 times 12, so,
SA=1809.557368, if you round it to two decimal places, it'll be,
1809.56, so the answer is 1809.56in. squared.
