A triangle has an area of 30 cm². The base and height are scaled by a factor of 3.

Volume  =  (4/3) pi  (diameter/2)^3  =

 

(4/3) (3.14) ( 8/2)^3

(4/3)(3.14)(4)^3

(4/3)(3.14) *64 =  

 

267.95 in^3

 

 

The triangle's new area  =

 

Old Area * (Scale Factor)^2   =

 

30  * (3)^2  =

 

30 * 9  =

 

270 cm^2
