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 for Q.1 = 4/9
Answer for Q2. = 2/3
Answer:
8.2 + 5y = 24 is y = 3.16
y = -42 = 0
c=1
y=1
Step-by-step explanation:
i think these confirm to graphs if i'm wrong just tell me and i'll edit my question.
Depends on the fraction to determine your answer
There are a couple of ways to tackle this one, using the 45-45-90 rule or just using the pythagorean theore, let's use the pythagorean theorem.
the angle at A is 45°, and its opposite side is BC, the angle at C is 45° as well, and its opposite side is AB, well, the angles are the same, thus BC = AB.
hmmm le'ts call hmmm ohh hmmm say z, thus BC = AB = z.
