​

Answer 1

Answer:

MARK ME AS BRAINLIEST

Step-by-step explanation:

Total surface area of cone=πr  

2

+πrl (r=Radius, l=slant height)

⇒704=πr(l+r)

⇒704=  

7

22

​ ×7(7+x)

⇒  

22

704

​ −7=l

⇒l=25cm

Answer 2

Answer:

total surface of area of cone =pie (l+r)

.. 704 = 22/7 × 7 (l+7)

704 / 22 =l+7

32 = l+7

32-7 =l

l=25 cm.

the slant height of the cone is 25 cm.
