Convert 15 2/3 to an improper fraction;

- 15 × 3 + 2/3 - 5 2/3

Simplify 15 × 3 to 45

- 45 + 2/3 - 5 2/3

Simplify 45 + 2 to 47

- 47/3 - 5 2/3

Convert 5 2/3 to an improper fraction

- 47/3 - 5 × 3 + 2/3

Simplify 15 + 2 to 17

- 47/3 - 17/3

Join the denominators

-47 - 17/3

Simplify

- 64/3

Convert to a mixed fraction;

<u>-21 \frac{1}{3}</u>

What is the approximate area of the shaded sector in the circle shown below?
Anton [14]

Answer:

The approximate area is A) 5.09cm²

Step-by-step explanation:

Area of a Circle = πr²

r = 1.8

Plug in our values

π(1.8cm²)

Evaluate the area of the entire circle

a = π(1.8cm²)

a = π(3.24cm)

a = 10.179cm²

Area of a sector, with the area of the circle of the sector being a = theta/360 * a

Evaluate the area of the sector

180/360*10.719cm²

0.5 * 10.179cm²

5.0895cm²

Round the value up

5.09cm²
