Answer:
7/10 pi (radians)
Step-by-step explanation:
The formula for sector area is (angle * r^2)/2
140pi = angle*r^2/2
multiply both sides by 2
280pi = angle * r^2
r = 20 cm (substitute)
280pi = angle * (20)^2
280pi = angle * 400
Divide both sides by 400
7/10 pi = angle
Answer:
3355
Step-by-step explanation:
55 x 61 = 3355
Answer: Length is 15 and width is 91
Step-by-step explanation:
If the length is 16 more than 5 times the width, that means:
let's say
x=length
y=width
2x+2y=212
If the length is 16 more times than 5 times the width, that means
y=5x+16
now we can substitute all y's for 5x+16:
2x+(5x+16)2=212
=2x+10x+32=212
=12x+32=212
=12x=180
x=15
If the length is 15, the width is
15*2+2y=212
=30+2y=212
=182/2
y=91
