* ANSWER PLS TY!! * Find the surface area of this cone.

vagabundo [1.1K]

Answer:

Step-by-step explanation:

Given,

R = 8 m

H = 15 m

Slant height :

$= \sqrt{ {r}^{2} + {h}^{2} }$

$= \sqrt{ {(8)}^{2} + {(15)}^{2} }$

$= \sqrt{64 + 225}$

$= \sqrt{289}$

$= \sqrt{ {(17)}^{2} }$

$= 17 \: m$

Now, Finding the surface area of the cone:

$\pi \: r(r + s)$

Plugging the values:

$= \pi \: \times 8(8 + 17)$

$= 8\pi \: \times 25$

$= 200 \: \pi$

Hope this helps...

Good luck on your assignment...

Find the 4th term of the expansion of (a - sqrt(2)) ^ 8

charle [14.2K]

Answer:

Applying the binomial theorem

$(x+a)^{n}=\sum _{k=0}^{n}{n \choose k}x^{n-k}a^{k}$

Here we have x = - $\sqrt{2}$ , n = 8,

=> 4th term (k = 3) would be:

${8 \choose 3}x^{8-3}a^{3}} = {8 \choose 3}(-\sqrt{2})^{5}a^{3}} = -224a^{3}\sqrt{2}$

Hope this helps!

3×0.7= <br> And could you please do the model

otez555 [7]

Answer: 2.1, I don't really know how to show a model for this, its just that when you multiply 3 and 7 you get 21, when you do 0.7 and 3, you just put the decimal place between the 2 and 1.

Select the property of equality used to arrive at the conclusion. If x - 3 = 7, then x = 10

goldenfox [79]

X - 3 = 7
add 3 to both sides
x - 3 + 3 = 7 + 3
x = 10
