Question

Circle A has a radius of 6.0 cm. The shortest distance between B and C on the circle is 5.4 cm.

What is the approximate area of the shaded portion of circle A?


16.2 cm²

21.0 cm²

37.7 cm²

113.1 cm²

Answer 1

• Length of arc=l=5.4
• Radius=r=6cm

`\\ \sf\longmapsto Area=(1)/(2)lr`

`\\ \sf\longmapsto Area=(1)/(2)(5.4)(6)`

`\\ \sf\longmapsto Area=16.2cm^2`
