Question

area of a sector whose radius is 3.5 cm and angle is 45 degrees​

Answer 1

Given-

theta=> 45°

Radius = 3.5 cm

_______________

Concept have to find out -.

Area of sector => ????

_______________

Formula used .-

$area \: of \: sector = > \frac{theta}{360} \times \pi \: {r}^{2}$

_______________

Solution..-

Theta => 45°

R@dius => 3.5cm

$area \: of \: sector = > \frac{45}{360} \times 3 .14 \times 3.5 \times 3.5 \\ \\ = > > > \frac{45}{360} \times 38.465 \\ \\ = > > > 4.80c {m}^{2}$

Some other important formula...

✨ Circumference of circle => 2πr

✨ Radius => d/2

d => diameter

✨Area of circle => π r²
