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?

- anonymous

please answer quicly :)

- TheEdwardsFamily

I thought was going to be easy...

- anonymous

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

- anonymous

please hurry ....

- Vocaloid

1:30 means that, to get the actual dimension, multiply each dimension on the drawing by 30

- Vocaloid

for example, if the measurement is 2 inches, then the actual dimension is 60 inches

- anonymous

oh ok thanks :) i have another one

- anonymous

find the area of a diamond of 10 inches?

- Vocaloid

10 inches what? 10 inches on each side? 10 inches across?

area = pi*r^2

- Vocaloid

is 10 the radius or the diameter??

ok, so
r = (1/2)*diameter = ?

- anonymous

- Vocaloid

read the problem again. think carefully.

- Vocaloid

(1/2)*diameter = ?

- anonymous

5

- Vocaloid

good, so r = 5
area of circle = pi*r^2 = ?

- anonymous

is 5 the answer?

- anonymous
