heat

A copper ball with a radius of 1.5 cm is heated until its diameter has increased by 0.20 mm. Assuming a room temperature of 22°C, find the final temperature of the ball.

What have you tried?

well, I know that the coefficient of linear expansion for copper is 17 x 10^-6, so it's coefficient of volume expansion is 3 times that.. and I know that the volume has changed by about .54. I'm not really sure what to do with this though

[dphoos]

I assume I'm using the equation delta V = BV(delta T), but when I do this I get a huge number

nevermind, I got it. I was subtracting 22 instead of adding it. The answer is 410.27 right?
