ANSWER
The slant height is 40cm.
EXPLANATION
The lateral area of a cone is given by:

where r=10cm is the radius of the circle and l is the slant height.
It was also given that, the lateral area is 400π cm²
We substitute the values to get,

We now divide both sides by 10π.
This implies that,


Hence the slant height is 40cm.
they increased by 70 percent. divide 667 by 912 and you get 0.67237903 but you round to the tenths and get 70% because you move the decimal to the right twice
