The area of the larger ttaingle is 12 cm squared
The area of the sector (As) of a circle may be calculated by the formula,
As = (a / 360) x π x r²
where a is the measure of angle in degrees and r is the radius. Substituting the known values,
As = (18 / 360) x 3.14 x (4²) = 2.512
Thus, the area of the sector is approximately 2.512 squared units.
Answer:
p: (-4)2 > 0
r: Two angles, whose measure have a sum of 90, are supplements.
