Answer:
Step-by-step explanation:
The total surface area of the sphere = 2πr²
Total surface area of the cylinder = 2πr²+2πrh
Total surface area of the solid = 4πr²+2πrh
r is the radius of the sphere and the cylinder
h is the height of the cylinder
Total surface area of the solid = 2πr(r+h)
If the total height of the solid is 18 cm, then r+h = 18cm
Given the Total surface area of the solid = 205π cm
205π = 2πr(r+h)
205π = 2πr(18)
205π = 36πr
205 = 36r
Divide both sides by 36
205/36 = 36r/36
r = 5.69cm
Since r+h = 18cm
5.69+h = 18
h = 18-5.69
h = 12.31cm

Step-by-step explanation:
interger/1 = rational number (anyt that can be expressed as a fraction)
to get the equation of any straight line, we simply need two points off of it, hmmm let's use (0 , 10) and (8 , 30) from the table
Answer:
266.67
Step-by-step explanation:
120=.45(x)
x=266.67
Answer:
$15.56
Step-by-step explanation:
So start by doing a 10% tip, because you just move the decimal place over by 1, so $1.35, and then divide that by 2 to get 5% which is .68, and add them to get 2.03. You can get the same answer by multiplying 0.15 to 13.53. 13.53 + 2.03 is 15.56. Hope this helped and have an awesome day!
