The area is 254.34 you had to do pi (3.14) x 9 x 9 since 9 is the radius
Simpliflyed answer would be 3a -21
Answer:
D
Step-by-step explanation:
Probability of falling NOT in the shaded region is "area of white region" <em>divided by</em> "area of whole rectangle (big one)".
<u>Area of whole rectangle:</u>
Area of rectangle = length * width = 10 * 5 = 50
<u>Area of White Region:</u>
First, area of shaded region = length * width = 4 * 2 = 8
Now,
Area of white region = area of whole rectangle - area of shaded rectangle
Area of white region = 50 - 8 = 42
Hence, probability is
0.84 = 84%
Answer choice D is right.
Answer:
B)
Step-by-step explanation:
to find the volume we need to find first the area of the triangle, and then multiply by 11 which is the length of the prism:
the measurements are:
the area of the triangle in one side is:
and now to find the volume of the prism we multiply the area of the triangle by the length of the prism:
which is option B)
