Question

Volume & Surface Area, Area of SectorsBA = 6.5 cm

Answer 1

Step-by-step explanation:

BA = radius

Radius = 6.5cm

< ABC = 23 degrees

pi = 3.14

`\begin{gathered} \text{Area of a sector = }(\theta)/(360)\cdot\text{ }\pi\cdot r^2 \\ \text{Area of a sector = }(23)/(360)\text{ x 3.14 x 6.5 x 6.5} \\ \text{Area of a sector = }\frac{23\text{ x 3}.14\text{ x 6.5 x 6.5}}{360} \\ \text{Area of a sector = }(3051.295)/(360) \\ \text{Area of a sector = 8.5 cm}^2 \end{gathered}`

Therefore, the area of a sector is 8.5 square cm
