what is it?
on a scale drawing of 1 : 30, what do you have to do to each measurement to get the actual dmension?
um, idk. never mind
I was here first O.O I CLAIM THIS QUESTION. I'm kidding of course. A second opinion is always helpful. So the question is about dimensions?
please answer quicly :)
I thought was going to be easy...
I'm rubbish with dimensions. Especially one so vague as this one.
please hurry ....
1:30 means that, to get the actual dimension, multiply each dimension on the drawing by 30
for example, if the measurement is 2 inches, then the actual dimension is 60 inches
oh ok thanks :) i have another one
find the area of a diamond of 10 inches?
10 inches what? 10 inches on each side? 10 inches across?
10 inches of a circle
can you put up a picture or something?
how do you find the area of a circle
area = pi*r^2
is 10 the radius or the diameter??
what is the area of the circle that has a diamond of 10 icnhes?
is there a picture?
oh, do you mean "diameter", not "diamond"?
...eh... I got nothing then, the question is too vague
im sorry i meant diameter
what is the area of the circle that has a diameter of 10 icnhes?
ok, so r = (1/2)*diameter = ?
um,, idk :(
read the problem again. think carefully.
(1/2)*diameter = ?
good, so r = 5 area of circle = pi*r^2 = ?
is 5 the answer?
what is pi?
pi is approximately 3.14
yes, the area of the circle is about 78.5, or 25pi
ok thanks :)
