Ok, so;

Let me draw the figure here below:

We know that the area of a circle can be found using the next equation:

Area = πr².

Where r is the radius and π is a number.

So, the area of this circle, will be:

Area = π(1km)²

Area = π km²

If p(a) = 1/3, p(b) = 2/5, and p(a ∪ b) = 3/5, then p(a ∩ b) =

Mumz [18]

P(a ∪ b) = p(a) + p(b) - p(a ∩ b)
p(a ∩ b) = p(a) + p(b) - p(a ∪ b)
p(a ∩ b) = 1/3 + 2/5 - 3/5
p(a ∩ b) = 2/15

[~Answer Explanation~]:

First:

Convert any mixed numbers to fractions.

Reduce fractions where possible.

Then your initial equation becomes:

356÷72

Applying the fractions formula for division,

=35×26×7

=70/42

Simplifying 70/42, the answer is

=1 2/3

Solve for U 11=8+u/7.68

BlackZzzverrR [31]

$\begin{gathered}\\ \sf\longmapsto 11=\frac{8+u}{7.68}\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 11 = \frac{8 + u}{ \frac{192}{25} } \end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 11=\frac{(8+u)×25}{192}\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 11=\frac{200+25u}{192}\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 2112=200+25u\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 2112-25u=200\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto -25u=200-2112\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto -25u=-1912\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto u=\frac{1912}{25}\end{gathered}$

Alternate form:

u=76.48

Which expression is equivalent to the expression shown? 7^14 divided by 7^2

uysha [10]

I am assuming you are trying to write seven to the power of fourteen and seven to the power of two, and if that is what you meant the correct answer is 13841287201.

Explain the difference between a square pyramid and a square prism.

Maslowich

The square pyramid looks exactly how it sounds. The base of the shape is a square and has 4 isosceles triangles that meet at a point. The square prism is like a 3D rectangle. It has 4 rectangles and 2 squares to close the shape.
Hope this helped.
