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.
Answer:

Step-by-step explanation:
Answer:
B. Scalene and D. Acute
Step-by-step explanation:
Check each answer.
A. Equilateral
All sides or all angles are not equal. So it is not equilateral.
B. Scalene
All sides are unequal. So it is scalene.
C. Obtuse
No any angle is greater than 90°. So it is not obtuse.
D. Acute.
All angles are less than 90°. So it is acute.
E. Isosceles
No two sides are equal. So it is not isosceles.
F. Right
No angle is 90°. So it is not right
Therefore, only answers B. Scalene and D. Acute are correct.
