The lateral area of the cone is 400 pi cm squared. the radius is 10 cm. find the slant height of the nearest tenth.

40 cm

Step-by-step explanation:

Given: The radius of the cone = 10 cm

The lateral area of the cone cm squared.

The lateral surface area of cone is given by :-

, where r is the radius and l is the slant height of the cone.

For r=10 and L.S.A. , we have

Hence, the slant height of the cone is 40 cm.

you can't solve x because it is 2 linear equation and you only have one equation

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
