Question

find area of shaded region

Answer 1

Answer:

6.125cms².

Step-by-step explanation:

LET RADIUS OF QUADRANT BE R = 3.5cms and triangle's base and height be 2cms and 3.5cms respectively,

AREA SHADED = AREA OF QUADRANT - AREA OF RIGHT TRIANGLE

                          ⇒ πR²\4 - 1\2 * base * height

                          ⇒ 22 * 12.25\28 - 7\2

                          ⇒ 9.625 - 3.5

                          ⇒ 6.125cms².

Answer 2

Answer:

Step-by-step explanation:

Radius of sector =3.5cm

Theeta=90°

Use sector formula=theeta /360×phi r^2

=90°/360×22/7×3.5^2

=9.625cm^2

Then area of triangle=1/2×b×h

Base =3.5cm

Height=2cm

=1/2×3.5×2=3.5cm^2

Area of sector minus area of triangle=9.6-3.5=6.1cm^2

Therefore area of shaded region =6.1cm^2
