Answer:
150.72 cm^2
Step-by-step explanation:
The blue area has an angle of 120 degrees, and 120/360 = 1/3, which shows that the blue area is 1/3 of the circle. In that case, the blue area is just 144pi/3. That simplifies to 48 pi.
48*3.14 = 150.72
5x+x-3=9
6x-3=9
cancel out 3 3+3 9+3
6x=12 divide six by 6 and by 12 too.
x=12/6=2
x=2
Given,
∠AOE = 30°
∠DOB = 40°
So, ∠EOD = 180 - (30+40) [angles on a straight line]
= 180 - 70
= 110
∠EOD = ∠COF [ vertically opposite angle]
∴ ∠COF = 110°
The expressions is undefined in the set of the real numbers.
54 = 2 × 3 × 3 × 3 ( as a product of its prime factor ).
