Question

[50 Points help!] A circle graph shows that an office supply store spends a total of $1200 per month on expenses. If the company spends $300 on paper, what would be the measure of the central angle for paper in the circle graph?

A. 75 degrees

B. 90 degrees

C. 120 degrees

D. 150 degrees

E. 175 degrees

Answer 1

b) 90 degrees

Explanation:

Forming the expression,

→ 360° × (300/1200)

Let's solve given expression,

→ 360° × (300/1200)

→ 360° × (1/4)

→ (360°/4)

→ 90°

Hence, the answer is 90°.

Answer 2

• B. 90 degrees

Explanation:

The circle represents a 360° angle.

Total spending corresponds to full circle and part of it spent on paper.

The ratio of paper over total is:

• 300/1200 = 1/4

This is the part of circle which is:

• 360°*1/4 = 90°

Correct choice is B.
