I don’t know this answer but I think it’s 81
Answer:
28.2743 square feet (28 square feet, rounded)
Step-by-step explanation:
The area of a circle is given by the equation
Area = πr^2
Plug in 3 for the radius
Area= π(3)^2
3 squared is 9
Area= 9 π
Area= 28.2743 square feet
Rounded to the nearest square foot, the area of the circle is 28 square feet.
Answer:
55.3
Step-by-step explanation:
19.9% of 278 = 55.322
55.322 rounded to the nearest tenth = 55.3
A.) All parallelograms are trapezoids
For A:
You add the probabilities to get the answer to A: = .75, or 3/4
Note that the probability of ALL THREE of them hitting would be 1/3 x 1/4 x 1/5.
For B:
2/3 and 3/4 is the probability of the other two people MISSING (the remainder of 1/3, 1/4)
1.0 = 100% chance to hit the target, so 1.0 x 2/3 x 3/4 = 1/2
Mark's chance of hitting is 1/5, so do 1/2 x 1/5, = 1/10
