Describing the Surface Area of a Cone Quick
Check
Which statements about the surface area of a cone are true? Check all that apply.
A cone is similar to a pyramid, but a cone has a circular base.
The equation for the base area of a square pyramid is the same as that for the base area of a cone.
The lateral area of the cone is -c1, where Crepresents the circumference of the base and I represents the slant
height.
The slant height is the distance from any point on the circular base to the vertex.
The surface area of the cone is the product of the base area and the lateral area.

Intro

x=10 and y= 8.

Step-by-step explanation:

Given that the cost of 1 banana = $0.60

Cost of 1 mango = $1.50.

Total cost= $ 18  

Here, x be the number of bananas and y be the numbers of mangos,

As the number of bananas is 2 more than the number of mangos,

So, x=y+2

Cost of x bananas

Cost of y mangos

Total cost = 0.6x+1.5y

Solving both the equations (i) as well as (ii), graphically as shown in the figure by plotting both the graphs.

Both the graphs intersect at the point (10,8) as shown in the graph.

So, the solution of both the equations is, (x,y)=(10,8). i.e

The number of bananas = x= 10 and

the number of mangos = y = 8.
