a.
2.6 cm
b.
1.7 cm
c.
2.8 cm
d.
1.5 cm

Respuesta :

Answer:

2.8 option (c)

Step-by-step explanation:

Radius of cone= 37 cm

let slant height of cone l

As we know, curved surface area of cone=πrl

Also, curved surface area of cone =103 π [tex]cm^{2}[/tex]

so, π r l= 103π

[tex]\frac{22}{7}[/tex]×37×l=103π

l=  [tex]\frac{103}{37}[/tex]

l=2.7837.....

l= 2.8 ( to nearest tenth)

Hence , the correct answer is option(c)
