This is asking you to solve the equation or to graph it.
Answer:
Step-by-step explanation:
Area of a circle is pi r squared.
So 3.142 times the radius squared.
They gave you the diameter(d), that's the distance all the way across. You need the radius(r), which is one half of the diameter. 7 divided by 2.
3.142X3.5squared=
Well, 3.5 squared is 3.5X3.5=12.25
So, then 3.142X12.25=38.4895
Now, we round. Second decimal place is an eight, followed by a nine. Five or above means round up.
38.49
Answer:
y = 2x + 6
Step-by-step explanation:
10x - 5y = -30
-5y = -10x - 30
y = 2x + 6
Answer:
3 11/25 pints of white paint
Step-by-step explanation:
8 6/10 is the same as 43/5
if 3/5 of the total pints are blue then 2/5 are white
so multiply 43/5 x 2/5 to get 86/25 which equals 3 11/25
