Question

Ted’s farm has 4 horses, 12 goats, 2 sheep, and 18 cows. Find the angle measure of the sector of a circle graph that represents each animal. Enter the correct answers in the boxes.

Answer 1

horses:40°

goats:120°

sheeps:20°

cows:180°

Explanation:

4+12+2+18=36 (total number of animals)

360°÷36=10° (a circle has a angle of 360°)

This means that 1 animal is 10°

horses: 4 × 10° = 40°

goats: 12 × 10° = 120°

sheeps: 2 × 10° = 20°

cows: 18 × 10° = 180°
