The circumference of a circle is 2PiR or PiD (Pi being 3.14) ( 2 x Radius x 3.14).
We have the diameter, 6. The radius is 0.5d or d/2.
Our radius is 3.
3.14 x 2 = 6.28
6.28 x 3 = 18.84
Your circle's circumference is 18.84 mm^2.
I hope this helps! :)
To find the probability of landing on a triangle, you will want find the combined areas of the triangles and the total area of the square target.
Divide the area of the combined areas and the total area to find the probability of landing on a triangle.
A = 1/2bh
1/2 x 8 x 8
A = 32 square inches
32 x 4
128 square inches (areas of triangles)
A = bh
26 x 26
A = 676 square inches
128/676 = 0.189
There is an approximate probability of 0.19 of hitting a triangle.
Answer:77d-16
Step-by-step explanation:
W=0.9
So w = 0.9 and v = -4
