Area of a circle is pi x r ^2
R = diameter/2
R = 1.8/2 = 0.9
Area = 3.142 x 0.9^2
Area = 2.5 square cm.
Answer:
23.83, The equation = (37.93 - (30 x 0.47))
Step-by-step explanation:
30 x .47 = 14.1
-18+4x
2(2x-9)
4x=18
-4x=-18
x=18/4
-x=-18/4
Hello,
f(x)=2x^2-3x+4
f(3a)=2(3a)^2-3*(3a)+4=2*9a²-9a+4=18a²-9a+4
