What is the lateral area of the cone to the nearest whole number? The figure is not drawn to

Sveta_85 [38]

Answer:

The lateral surface area of the cone is $25120\ m^2$ .

Step-by-step explanation:

We have.

Height of a cone is 60 m

Diameter of a cone is 10 m

Radius, r = 80 m

The lateral surface area of a cone is given by :

$A=\pi rl$

l is slant height of the cone,

$l=\sqrt{60^2+80^2} =100\ m$

Plugging all values in above formula,

$A=3.14\times 80\times 100\\\\A=25120\ m^2$

So, the lateral surface area of the cone is $25120\ m^2$ .

What is the solution to the system x+y=10 3y=-3x+30 PLEASE helpppp

choli [55]

Answer:

Step-by-step explanation:

x+y=10

x=10-y

x=10-5

x=5

3y= -3x+30

3(10-y)= -3(10-y)+30

30-3y= -30+3y+30

30+30-30=6y

30=6y

y=5

Simplify (x^3/8)^3/4

Viktor [21]

When an exponent is raised to another exponent, you can multiply the powers to simplify them.

3/8*3/4

*Multiply numerators*

3*3=9

*Multiply denominators*

8*4=32

x^9/32

Hope this helps!!
