Answer:
9.42
Step-by-step explanation:
The radius is always half of the circumference. So u would do 18.84 divided by 2.
Answer:
y=140°
Step-by-step explanation:
Method 1.
The exterior angle theorem tells us that y=20+120=140
Method 2.
Solve for x first., then use that to solve for y.
The sum of the interior angles of a triangle is 180, so we can get x by doing 180-20-120=40.
y and x make a straight angle which is 180°, so we can get y by doing 180-40=140
Answer:
1.) 88cm
2.) 3
3.)104
Step-by-step explanation:
1) circumference= 2πr
2×22/7×14 = 88cm
5y+8=0 --> 5y = -8 --> y = -8/5
I got 499.2 multiplying 10.4•5•8
