Answer:
see below
Step-by-step explanation:
First we need to find the radius
r =d/2 = 15.8/2 = 7.9 cm
The area of a circle is given by
A = pi r^2
= pi ( 7.9) ^2
=62.41 pi
Using 3.14 for pi
195.9674
To the nearest hundredth
195.97
Using the pi button
196.0667975
196.07
It is associative property
35-(-8)=35+8=43
~~~~~~~~
9
easy question, 3x9=27
I think it would be A
900
Sum of interior angle for a polygon = (n-2)180
7 sides
=(7-2)180
=5*180
=900
