Question

Mrs Lawson plants roses in 2/9 of her circular flower garden. What is the angle measure of the section that includes roses?

Answer 1

Answer: 80 degrees

A whole circle has 360 degrees, which can be represented as:

`2\pi=360\º=(9)/(9)=1circle`

If we want to find the angle measure of the section that includes roses (2/9 of a circle) we can multiply the 360 degrees that represents the whole circle by the fraction of the circle that is with roses:

`360\º((2)/(9))=80\º`

Hence, the angle measure of the section that includes roses is 80 degress
