I suck at math

[Smokey_locs2006]

I'm doing this math test.. and yeah.. I suck at it. So I ask you for help Charas what the hell is these answer to this problems.

1.

Find the circumference of a circle with a diameter of 45m. Use 3.14 for pi.




2.
Find the area of the composite figure. Use 3.14 for pi. Area of circle is
 Pi r ^2



I must have been in class the day we went over these.. if any of you can help me with these 2 I'd be very happy.

What is it, a take home test? Anyways, I know how to do circle stuff... I just... forgot.

Something like that.. The better grade I get the more money I get to go to school next year.. I think at one point I did know how to do number 2 but...I want to be 100% right.

Well, I think r= radius, whic is half the diameter of the circle. So if the diameter on 2 os 2ft, the radius is 1ft. So 1 sq = 1= 3.14 times 1= 3.14 in half for half a circle is 1.57 + 2x3 =1.57 + 6= 7.57 or somethin, I dunno. Just trying to group together random bits o math.

C= PiD
C= 3.14 * 45
C= 141.3

A(figure)= A(semi-circle)+ A(rectangle)
A(s)=[3.14(1)^2]/2 (its a semicircle so it is half the area)
A(s)=1.57
+
A(r)=3 * 2
A(r)=6
Area(figure)=6+1.57
Area=7.57 feet

Whoa, I got #2 right XD Unexpect'D!

Wait until you have to start graphing sinusodial functions using phase shifting. Granted, finding the sine of a line segment on the unit circle when given the tangent is harder and yet sounds easier.

Dude, that's easy stuff you're asking about. What are you in, remedial math? No offence, but you must REALLY suck at math.

Mean and uncalled for, but not without merit.

Agreed, but not really mean. Just uncalled for.

I admittingly suck at math.Im in algebra 1 right now, and the only thing Im finally starting to understand compound inequations with slopes and gra[hs and number lines and all that shtuff. Im proud of myself.

And sorta mean. You shouldn't insult someone like that.

Right now I actually got stuck in Algebra AB, which is the first half of Algebra 1 boo kand it takes a year. But we finished already and I took CD last year, so repeat for me! Stupid move of schools and the office idiots...... Grrrrrr...

I'm in advanced classes in school, which basically means I'm stuck in the higher math classes. Bad thing is math is my worst subject. I took Algebra 1 in 8th grade, 2 in 9th, and I'm taking Geom/Trigonometry this year. God, I hate math.
