Question

find the area of a 270degree sector with radius 3.5 cm​

Answer 1

Question = we have to find area of minor sector .

Given = @ = 270° , r = 3.5 cm

we know that,

area of sector =

$\frac{@}{360} \pi \: r^{2}$

putting values we get,

$\frac{270}{360} \times \frac{22}{7} \times \frac{35}{10} \times \frac{35}{10} \\ \\ = 28.875cm ^{2}$

Hope it helps you ..
