Answer:
Area = [tex]\frac{98}{9}[/tex] π
Arc Length = [tex]\frac{28}{9}[/tex] π
Step-by-step explanation:
Area of Sector = [tex]\frac{80}{360}[/tex] × π [tex](7)^{2}[/tex]
= [tex]\frac{98}{9}[/tex]π [tex]cm^{2}[/tex]
Arc Length = [tex]\frac{80}{360}[/tex] × 2π [tex](7)[/tex]
= [tex]\frac{28}{9}[/tex] π
[The Area of sector can be calculated using the formula: [tex]A = \frac{d}{360}[/tex] × π[tex]r^{2}[/tex] where d is the size of angle substended by arc and r is radius.]
[The Arc length can be calculated using the formula: [tex]L = \frac{d}{360}[/tex] × [tex]2[/tex]π[tex]r[/tex] where d is the size of angle substended by arc and r is radius.]
