Answer:
the chances are 1/4
Step-by-step explanation:
you have 1/4 chance you will pick the two angles that make 180 degrees or supplementary
Answer:
i dont know it (sad face)
Step-by-step explanation:
The option will be D, since I know that you shade below the line if y is less than. Additionally, the slope is -2. That eliminates A, so the only option left is D.
Half circle so 1/2 times area
area=pir^2
d/2=r
d=5
5/2=2.5=r
area=pi2.5^2=6.25pi=19.625
times 1/2 to find half area
1/2 times 19.625=9.8125

9.81 m²
Answer:
319
Step-by-step explanation:
So, to find the surface area, first we find the base area, which is: 11 x 11 = 121
Then, we have to find the area of the other faces. Since each face is a triangle, we can use the formula A = 1/2 x b x h.
So,
b = 11
h = 9
1/2 x 11 x 9 = 49.5
The, we multiply by 4, the number of sides: 49.5 x 4 = 198
Then, we add the 2, values: 121 + 198,
Which gives us: 319.
Hope this helped!
