How can I find the surface area of a right cone with a radius of 6 and slant height of 16

1 answer:

3 0

First, you have to calculate the height.
Pythagorean Theorem:
a^2+b^2=c^2
Slant height=c^2
Radius=b^2
So, a^2+6^2=16^2
a^2+36=256
a^2=220
a=14.832397
Surface Area = πr(r+ square root of h^2+r^2)

Surface Area is approximately 414.69

Trapezoid DEFG is dilated by scale factor of 2\3 to form trapezoid D'E'FG. Side E'F' measures 32. What is the measure of side EF

Mamont248 [21]

Answer: 48

Step-by-step explanation:

Given

Trapezoid DEFG is dilated by a scale factor of $\frac{2}{3}$

$E'F'=32$

Suppose the length of EF is $x$

Multiply the side length of DEFG by $\frac{2}{3}$ to form E'F'

$\Rightarrow E'F'=x\times \dfrac{2}{3}\\\\\Rightarrow 32=x\times \dfrac{2}{3}\\\\\Rightarrow x=16\times 3\\\Rightarrow x=48$

$\therefore EF=48$

Answer:

Let's solve for f.

fx=

4x−3

x−10

Step 1: Multiply both sides by x-10.

fx2−10fx=4x−3

Step 2: Factor out variable f.

f(x2−10x)=4x−3

Step 3: Divide both sides by x^2-10x.

f(x2−10x)

x2−10x

4x−3

x2−10x

4x−3

x2−10x

Answer:

4x−3

x2−10x

Let's solve for g.

gx=

2x−8

x−10

Step 1: Multiply both sides by x-10.

gx2−10gx=2x−8

Step 2: Factor out variable g.

g(x2−10x)=2x−8

Step 3: Divide both sides by x^2-10x.

g(x2−10x)

x2−10x

2x−8

x2−10x

2x−8

x2−10x

Answer:

2x−8

x2−10x

Answer:

True.

Step-by-step explanation:

Computers have been used to check odd numbers up to 10^300 and no odd perfect numbers exist in this range , but that is not a proof that they don't exist.
