Answer:
The area of the sector is 25.1327 cm²
Step-by-step explanation:
The area of a sector of circunference delimited by an angle in radians can be calculated by using the formula below:
area = (angle*r²)/2
area = [(4*pi/9)*(6)²]/2
area = [(4*pi/9)*36]/2
area = (144*pi/9)/2
area = 144*pi/18
area = 8*pi
area = 25.1327 cm²
The area of the sector is 25.1327 cm²
A = 1/2 * (b1 + b2) * h
b1 and b2 are the lengths of the bases of the trapezoid
h is the height
0.8 squares shaded out of 10
You just do 4x2 which is 8
Then add the 0. In front of 8
Easy as that
the square root of 42 is not a rational number, it is an irrational number
