Semicircle M has a radius of 15 inches. If an ant walks from A to B directly along diameter AB and a beetle walks from A to B around ACB. how much farther, to the nearest tenth of an inch, does the beetle walk?

(1) 17.1
(2) 32.1
(3) 64.2
(4) 79.2

A,17.1 in

Step-by-step explanation:

circumference of sphere=2πr

Beetle walks=πr=π×15=15π=15×3.14≈47.1 in

Ant walks=d=2r=2×15=30

difference=47.1-30=17.1 in
