Question

Radius
of a a sector of a circle
is 7 cm .If
the measure of the
arc of the sector is equal to three
right angles
find the
the sector of the circle​

Answer 1

Answer:

Area of sector = 115.5 cm^2

Step-by-step explanation:

Radius of the sector = 7 cm

value of π = 22/7

Measure of the arc = 3 x right angles = 3 x 90 = 270 degrees

thus, angle made at center = θ = 270 degrees

Area (Sector) = (θ / 360)  x π x r^2

==> 270/360 x 22/7 x (7)^2

==> 3/4 x 154

==> 3 x 38.5

==> 115.5 cm^2
