A dinner plate has a circumference if 100.48cm. What is the area of the dinner plate? (Use 3.14 for r)

803.84

Step-by-step explanation:

to get the radius you have to find the diameter  so take the circumfrence and divide by 3.14 and you end up with 32 and 32/2 is 16 so the radius would be 16 so square it to get 256 then multiply by 3.14 and you get 803.84

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
