I need to know the surface area of these

anastassius [24]

9514 1404 393

Answer:

245 cm²

Step-by-step explanation:

The surface area of a cone is given by ...

SA = πr(r +s) . . . . where r is the radius, and s is the slant height

Filling in the given values, we have ...

SA = (3.14)(3 cm)(3 cm +23 cm) = (3.14)(3)(26) cm² ≈ 245 cm²

The surface area of the cone is about 245 cm².

➷ The formula to calculate the circumference is $\pi d$

d is the diameter (double the radius)

Substitute the values in:

Circumference = (3.14)(3 x 2)

Circumference = 18.84

It would be option D. 18.84 m

I'm genuinely lost in any problems like this and my teachers are no help, I need help doing exponents in general, everything to

Stolb23 [73]

Answer:

See below.

Step-by-step explanation:

So we have the expression:

$(-6n^{-3})^2$

We can use the power of a product property, where:

$(ab)^n=a^n\cdot b^n$

So:

$=(-6)^2\cdot(n^{-3})^2$

For the left, -6 squared is the same as -6 times -6. This equals positive 36.

For the right, we can use the power of a power property. The property says that:

$(a^n)^k=a^{nk}$

So:

$(n^{-3})^2=n^{(-3)(2)}\\=n^{-6}$

So, all together, we have:

$=(-6)^2\cdot(n^{-3})^2\\=36n^{-6}$

We have the expression:

$-\frac{3x^0}{x^4}$

First, note that anything to the zeroth power (except for 0) is 1, thus, x^0 is also 1. Simplify:

$=-\frac{3}{x^4}$

And that's the simplest we can do :)

Notes for 6)

We <em>can</em> put the x^4 to the numerator. Recall that when you put an exponent to opposite side, you put a negative. In other words:

$x^n=\frac{1}{x^{-n}}$

And vice versa:

$\frac{1}{x^{-n}}=x^n$

So, we can write the above as:

$=-\frac{3}{x^4}\\=-\frac{3}{x^{-(-4)}}\\=-3x^{-4}$

However, traditionally, we want only positive exponents, so this wouldn't be correct.
