Answer:
28.3 (explaination below)! :)
Step-by-step explanation:
Use the formula for cicrumfrence: C=2πr
Radius can be found by splitting the given number in half, (unless you were given the radius already, then you'd just multiply by 2).
Plug in our numbers. C= 2π4.5
Then, multiply.
You'd get 28.27433388230814.
Rounding to the first decimal place, you'd have a final answer of 28.3.
Hope this helps!
<u>Answer:</u>
x = -4
<u>Step-by-step explanation:</u>
We are given the following word problem which we can solve by breaking it down into parts and translating it into numerical values:
Fourteen more than three times a number is 2.
1. Fourteen more than ---> + 14
2. three times a number ---> 3x (assuming the number to be x)
3. is 2 ---> = 2
So combining these, we get:
3x + 14 = 2
Solving this to get:
3x = 2 - 14
3x = -12
x = -12/3
x = -4
If you can describe a mathematical way to create the pattern, then the next number is mathematically predictable. Options B, C, D are like that.
The best choices are
A. Ask your friends
E. Use winning lottery numbers
Answer:
30.3
Step-by-step explanation:
First we find the area of the trapezoid. The formula for that is (b1+b2)/2(h)
2+10=12
12/2=6
6x4=24
To find the area of a semicircle we do πr²/2
2^2=4
4x3.14=12.56
12.56/2=6.28
24+6.28=30.28
That is extremely close to 30.3 so the paper must be a bit off.
