Hey there! Welcome to Brainly.
Let's solve using order of operations (PEMDAS), which is Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
First, we solve the parentheses.
9+6÷6
Now we take care of the division.
9+1
We add.
10
Therefore, your answer is 10
I hope this helps!
Formula to find the central angle is,
Where, s = arc length
r = radius
= central angle in radian.
According to the given problem,
r = 7 and 
.
First step is to plug in these values in the above formula. So,
By simplifying.
Since 
s=14.65
Hence, arc length iss 14.65 feet.
The shapes below that have a constant cross-section between a pair of faces are cylinder, cube, sphere, hexagonal, and prism.
<h3>What is the definition of geometry?</h3>
It is concerned with the geometry, region, and density of various 2D and 3D shapes.
A cylinder is a closed solid with two parallel circular bases and a curving surface connecting them.
The shapes have a constant cross-section between a pair of faces like a cylinder.
Hence,cylinder, cube, sphere, hexagonal, and prism are the forms below that have a constant cross-section between a pair of faces.

I was stuck on the same thing in my class test. I ended up failing but if I get the answers to it I’ll totally send them to you
id say its a rhombus. all the other shapes can have right angles
