Answer:
½pi or 0.5pi units²
Step-by-step explanation:
Area : angle
9pi : 2pi
x : pi/9
9pi/2pi = x/(pi/9)
4.5 × pi/9 = x
x = ½pi or 0.5pi units²
Circumference of a circle=diameter times pi
50.24=d(3.14)
d=16
radius is half of diameter so radius is 8
Area of a circle=pi(r^2)
(3.14)(8^2)=(3.14)(64)=200.96
Answer:
D.
Step-by-step explanation:
(4 x 8) + (4 x 3)=44
4 x (8 + 3)=44
Answer: a=3, b=1
A parallelogram have its opposite sides equal and parallel.
Step-by-step explanation:
SO, the quadrilateral WXYZ have its opposite sides equal as its a parallelogram.
From the given figure the side XY= WZ and XW= YZ, which gives two equations i.e
Equation 1 is 3a-4=a+2 and Equation 2 is b+1=2b
Solving Equation 1 Solving equation 2
3a-a = 2+4 2b-b = 1
2a = 6 b=1
a = 3
So, by solving the two equations a=3 and b=1.
