What is the question. Brainly won’t let me message you.
Answer:16
Diameter = 8
Radius= Diameter/2
=4
Circumference of a circle =2Πr
= 2×3.14×4
=25.12yards
Hence the circumference of the circle is 25.12
What type of angles are there
Well use the distributive property
-98=4x-2(5x+13)
Now multiply 2 times 5x+13
-98=4x-10x-26
Now combine like terms
-98=-6x-26
Now get 26 on the other side by adding it to -98
-6x=-72
x=12
