Answer:
4:25
Step-by-step explanation:
Given that,
r₁ = 15 inches, r₂ = 6 inches
The area of the cylinder is given by :

The ratio of surface areas of two cylinders,

Hence, the required ratio is 4:25.
For C highest to lowest
4/5, 3/4, 7/10, 1/2
For D
3/4, 17/24, 2/3, 7/12, 1/6
Answer:
4Z+16-Z²
Step-by-step explanation:
Given that,
D = Z+6
C = -2 + Z - Z²
We need to find the value of 3D+C.
So,
3D+C = 3(Z + 6)+(-2 + Z - Z²)
= 3Z+18-2+Z-Z²
= 4Z+16-Z²
So, the required expression is 4Z+16-Z².
Answer:
26
Step-by-step explanation: because thats my answer
Note that when dividing, and the base is the same, you can subtract the power signs.
(5^5)/(5^2) = 5^(5 - 2)
5 - 2 = 3
5^3 = a^b
Simplify.
5^3 = 5 x 5 x 5
5 x 5 x 5 = 125
c = 125
