I'm rubbish with dimensions. Especially one so vague as this one.

please hurry ....

  • Vocaloid
1:30 means that, to get the actual dimension, multiply each dimension on the drawing by 30
Vocaloid
  • Vocaloid
for example, if the measurement is 2 inches, then the actual dimension is 60 inches

can you put up a picture or something?
anonymous
  • anonymous
how do you find the area of a circle
Vocaloid
  • Vocaloid
area = pi*r^2
Vocaloid
  • Vocaloid
is 10 the radius or the diameter??
anonymous
  • anonymous
what is the area of the circle that has a diamond of 10 icnhes?
Vocaloid
  • Vocaloid

read the problem again. think carefully.
Vocaloid
  • Vocaloid
(1/2)*diameter = ?

  • anonymous
is 5 the answer?
anonymous
