Increases by +2
Its arithmetic
Sixth number would be 17+2=19
Seventh is 19+2=21
Eighth is 21+2=23
The answer is C. 89 in^2
This is found by (1/2(

))+70
r in this equation stands for radius which is half the diameter. Sice the diameter equals 7, the radius equals 3.5
You have to solve this by putting it into a calculator since you can't really solve for an equation with pi in it otherwise.
Hope this helps!
Answer:
7.5
Step-by-step explanation:
To find the median you must align all the numbers least to greatest so the order goes like this. 3,3,4,7,8,9,12,16. Then you must find the number in the middle. since there is not a number in the middle you add 7 and 8 together and then divide by 2 which is 7.5
Answer: t^2=-f-576/16
Step-by-step explanation:
Step 1. Switch the equation around:
-16t^2+576=f
Step 2. Subtract 576 from each side:
-16t^2+576-576=f-576
Step 3. Now simplify:
-16t^2=f-576
Step 4. Divide everything now by -16:
-16t^2/-16=f/-16-576/-16
Step 5. Simplify again:
t^2=-f-576/16
Hope I could help! :)
9 + (-4) = 5/2= 2.5
10 + 7 = 17/2 = 8.5
