Answer:
Step-by-step explanation:
Since area of a circle is pi.r^2
We know that diameter is 20
Radius is half of diameter
So it becomes
Pi.(d/2)^2
So pi.(40/4) is the area of this circle.
Or 40pi/4
Answer:
15 im positively sure
Step-by-step explanation:
The 6 sides are the same sides
so 6+6=12
add the 3
12+3=15
Slope = Change in y / Change in x
= 8 - 2 / 3 - 1
= 6 / 2
= 3
1 3 1×3 3
--- × --- = ------ = ----
2 4 2×4 8
5 5 5×5 25
--- × ---- = --------- = -------
6 7 6×7 42
hope is understandably
