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.
The correct answer is a.28/72
<span>The correct answer is option B. i.e. Transitive property. According to the transitive property of equality, if 8=x and x= y then, y = 8. This is mainly used in algebra and this property is a part of equalities and inequalities.</span>

Answer:
slope is 2
Step-by-step explanation:
find the change in y and x to then divide them
17-1/5- -3 = 16/8 = 2
