D, think as 13 dividing 2, you get 6 and have one left
Another triple integral. We're integrating over the interior of the sphere
Let's do the outer integral over z. z stays within the sphere so it goes from -2 to 2.
For the middle integral we have
x is the inner integral so at this point we conservatively say its zero. That means y goes from 
and 
Similarly the inner integral x goes between 
So we rewrite the integral
Let's work on the inner one,
There's no z in the integrand, so we treat it as a constant.
So the middle integral is
I gotta go so I'll stop here, sorry.
If you are talking about the area and perimeter of one of the triangular faces...
8 x 1.2 = 9.6
6 x 1.2 = 7.2
Perimeter = 9.6 + 7.2 + 7.2 = 24
Area = Linear Scale Factor²
1.2² = 1.44
7 x 1.44 = 10.08 (units)²
Step-by-step explanation:
Get the square root of 316 which is 17.8
To get surface area you do cross section area x6
17.8×17.8×6=1896
To get volume you do length ×height ×width
17.8×17.8×17.8=5639.752cm³ or 5640cm³ if rounded off
She travels, say 4 miles, stops gets gas and travels the rest of the way, 2 miles. She shops and then rides 6 miles back home without stopping. 6 miles there, 6 miles back. 6+6= 12!
She travels 12 miles! Hope this helps!
