Find the lateral area and surface area of cone

Mathematics
1 answer:
worty [1.4K]3 years ago
3 0

Answer:

\large\boxed{L.A.=168\pi\ in^2}\\\boxed{S.A.=232\pi\ in^2}

Step-by-step explanation:

The formula of a lateral area of a cone:

L.A.=\pi rl

r - radius

l - slant height

The formula of a surface area of a cone:

S.A.=\pi r^2+\pi rl

We have r= 8in and l = 21in. Substitute:

L.A.=\pi(8)(21)=168\pi\ in^2

S.A.=\pi(8^2)+168\pi=232\pi\ in^2

Find the equation of the straight line passing through the point (3, 5)
Ne4ueva [31]

Answer:

y = -1/3x + 6

Step-by-step explanation:

the slope is -1/3 because you find the the reciprocal and switch the sign. To find the y intercept you plug in the points to the equation.

5 = -1/3(3) + b

5 = -1 + b

6 = b

Create a table of data for two different linear functions. The table should use the same values of x for both functions. Based o
user100 [1]

Answer:

Yes they will intersect

Function 1= F(X)=2X+5

Function 2=H(X)=3X+2

INTERSECT=(3,11)

Step-by-step explanation:

First of all, we create 2 LINEAR function, i created the function f(x)=2x+5 and the function h(x)=3x+2, both are linear(without a quadratic term). Then

you replace the x for a number:

Table 1 (F(X)=2X+5)                                 Table 2 (H(X)=3X+2)

X=1----->Y=2+5=7                                     X=1------>Y=3·1+2=5

X=2---->Y=2·2+5=9                                  X=2----->Y=3·2+2=8

X=3---->Y=3·3+5=11                                  X=3----->Y=3·3+2=11

With both tables of data we can see that in the X=3/Y=11 point this two linear functions will intersect so the answer is that the two functions will intersect at (3,11)----->(X,Y)

Which of the following is a way that scientific advancements have benefited society? a. increased energy efficiency b. increased
PilotLPTM [1.2K]

The answer is a. increase energy efficiency.  This means that we now use less energy to do more thanks to many advances in technology.  It could also be due to the use of alternative sources of power such as the sun or win.  These new sources provide energy without causing pollution.
