If 16.1cm is a radius of circle:
# Area= Pi X R{2}
= 3.141592654 X 16.1 square
= 814.3 cm square
# circumference= Pi X 2 X R
= 3.141592654 X 2 X 16.1
= 101.2 cm
# if 16.1 is a diameter:
#Area= Pi X D/2 square
= 3.141592654 X 16.1 divide by 2 square
= 203.6 cm square
#Circumference= Pi X D
= 3.141592654 X 16.1
=50.6 cm
That's it it. a bit long cuz I dun know what exactly what they given Radius or Diametre.
Answer:
x=20
Step-by-step explanation:
use proportions
121:11
or 11:1
take 10 and multiply it by 11 to get the length of the other side.
110
set the equation equal to that length
5x+10=110
-10 on both sides
5x=100
÷5 on both sides
x=20
Answer:
(16, 6 )
Step-by-step explanation:
Basically you are expressing the points (dots ) in coordinate form
Locate x = 16 on the x- axis ( between 14 and 18 )
Then go vertically up to the point at (16, 6 )
Equals 10

The kast one is the answer. It is the only one unaffected by A to any degree.
