Answer:169pi
Step-by-step explanation:
Circumference(c)=26pi
Circumference(c)=2 x pi x radius(r)
26pi=2pi x r
Divide both sides by 2pi
26pi/2pi=(2pi x r)/2pi
13=r
Radius(r)=13
Area of circle=pi x r^2
area of circle=pi x 13^2
Area of circle=169pi
If lines a and b are parallel, then aº = 79º = dº = bº.
Answer:
let the no.s be : x, x+1, x+2
then,
=> x + x+1 + x+2 = 183
=> 3x + 3 = 183
=> 3x = 183 - 3
=> x = 180/3
=> x = 60
therefore, the whole no.s are 60, 61, and 62
