The lateral area of a cone is 103647-10-04-00-00_files/i02.jpg cm2. the radius is 37 cm. find the slant height to the nearest tenth.
a.
2.6 cm
b.
1.7 cm
c.
2.8 cm
d.
1.5 cm

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

so, π r l= 103π

×37×l=103π

l=  

l=2.7837.....

l= 2.8 ( to nearest tenth)

Hence , the correct answer is option(c)
