1. what is the lateral area of the cone to the nearest whole number? the figure is not drawn to scale.(50 m cone) 49,009 m 18,850 m2 98,018 m2 94,248 m22. 2. what is the slant height of the cone to the nearest whole number? the figure is not drawn to scale.(17m cone) 21 m 19 m 17 m 18 m

1)

S=48984 m^2

2)

slant height=19 m.

Step-by-step explanation:

1)

The height(h) of cone is given by: 50 m.

Diameter of cone is: 240 m.

Also radius(r) of cone is:240/2=120 m.

The lateral surface(S) area is given by:

Hence, lateral surface area of cone= 48984 m^2.

2)

We are given that radius(r) of cone=9 m.

Height (h) of cone = 17 m.

Slant height(l) of cone is given by:

Hence, slant height is 19 m.

step-by-step explanation:

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
