Answer:

r = 29.82

Step-by-step explanation:

We have the equation r/7.1 = 4.2 and are asked to solve for r.

To solve, we need to isolate r, do as followed and multiply 7.1 from both sides:

r/7.1 = 4.2

r = 29.82

Answer:

r = 29.82

Step-by-step explanation:

\frac{r}{7.1} = 4.2

The opposite of division is multiplication, you will need to multiply 7.1 to both sides.

That would leave:

r = 4.2 (7.1)

r = 29.82

If there are further instructions for rounding, you can round.

Have a nice day!

How can you find the surface area of a composite solid made up of prisms ? (Help)
sammy [17]
Oh, this is easy. For any prism, you find the surface area by finding the are of all the sides. I will post all surface area formulas here, for reference
Cube:



Surface area = 6 × a2




Right circular cylinder:



Surface area = 2 × pi × r2   +  2 × pi × r × h

pi = 3.14
h is the height
r is the radius


Rectangular prism:



Surface area = 2 × l × w  +  2 × l × h  +  2 × w × h 




l is the length
w is the width
h is the height


Sphere:



Surface area = 4 × pi × r2 

pi = 3.14
r is the radius


Right circular cone:



Surface area = pi × r2  +  pi × r ×( √(h2 + r2)) 

pi = 3.14
r is the radius
h is the height
l is the slant height 


Right square pyramid:



Surface area = s2 + 2 × s × l

s is the length of the base
h is the height
l is the slant height
