Question

Find the area of a quadront of a cirde whose radius is 3.5cm​

Answer 1

Answer:

9.63 cm

Step-by-step explanation:

area of quadrant of a circle= 1/4× area of circle

given, r=3.5cm

therefore, area of a circle= π×(r^2)=22/7×(3.5^2)=38.5cm

hence, area of a quadrant=1/4×38.5=9.63 cm (approx)

Answer 2

Answer:

9.625 cm^2 is your answer

Step-by-step explanation:

it is a given that,

OACB is quadrant

Given radius :- 3.5 CM

we know that

Area of quadrant OACB =1/4×area of circle

Area of quadrant OACB =1/4πr^2

=1/4×22/7×(3.5) ^2

=1/4×22/7×3.5×3.5

=9.625 cm^2

hope you understand my answer...
