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:
26 million
Step-by-step explanation:
8200000 / 0.32 = 25625000
25625000 rounded to nearest million = 26 million
As we know
area of triangle = 1/2 *height*base
32=1/2*8*base
32=4*base
8 =base
Y+3=0 is vertical line -3 on the graph.
Hope this helps there was no choices.
