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:
the first one is 192 and the second is 396 the third is 216 the fourth is soapy suds
Step-by-step explanation:
the first you just do 4x6x8
the second you just do 9x8x11 and then divide by 2
the third you just multiply 9x6x4 or you could do 3x4x9 and multiply that by 2
the fourth is soapy suds bc it has a larger volume of 1248 while clean and bright only has a volume of 936
Answer: 2
each counter is 1/8, so two is 2/8 which is equivalent to 1/4
(2,0)
the first # is the x coordinate which is left and right. Since B is 2 to the right from the center (0,0) x is 2. Left would make it negative
The second # is the y coordinate which is up and down. Since B is on the x axis the y coordinate is 0.
