Question

Quadrant with radius 7 cm. find the circumference​

Answer 1

Answer:

_______________________________________________

We have,

R = 7 CM.

Area of quadrant =

$\frac{1}{4} \times \pi \: {r}^{2}$

$\frac{1}{4} \times \frac{22}{7} \times 7 \times 7$

$38.5 \: c {m}^{2}$

Answer 2

A quadrant is 1/ fourth of a circle so circumference of a quadrant will be 1/4 of the circumference of its circle
Circumference of a circle is equal to 2x3.14xr so circumference of a quadrant is 1/4x2x22/7xr

= 1/4x2x22/7x7
=22/2=11

So your answer is 11 cm
