Answer:
the second bubble is the answer
Step-by-step explanation:
Answer:
The answer is 350 points
Step-by-step explanation:
The Area of a circle is πr∧2
The problem states that in the attempts, you never hit the outermost ring in the 10 attempts so we need the area of the 1cm and 2cm circles
Area of the 1st circle; π X 1∧2 = π
Area of the Second circle; π X 2∧2 = 4π
We also need the area which is the difference between the area of the 1cm and 2cm circle
4π - π = π
Points 50 = π/4π = 1/4
points 30 = 3π/4π = 3/4
For one attempt,
E(x) = 50 x 1/4 + 30 x 3/4
= 12.25 + 22.5
= 34.75
This is approximately 35
Therefor, 10 individual attempts will be 10 x 35 = 350
The answer is 12 ÷ 3
Step-by-step explanation:
12 ÷ 3

Take a look at it. We know it's a cone, right? So that answers your 3rd question. The base (or the part that it sits on if you put it down), is a circle. The other parts it can't sit on without rolling, so it has to be that circular side. And if that's a circle, that means that any line from the center to the outside 'circumference' is the radius. This means that the answer is A.
Well the question is written wrong but I think is 30
