(B) 16.5π
<u>Explanation:</u>
The shape given is a cylinder
The height, h of the cylinder = 4cm
Diameter of the cylinder = 3cm
Radius, r = 1.5 cm
Surface area of cylinder, A = ?
We know:
Surface area of cylinder = 2πrh + 2πr²
Therefore, the surface area would be 16.5π
Answer:
Step-by-step explanation:
so its 36+9 = 45
36/45=4/5
X=5.5 is what I got when I did the math
Answer:
7(x)-21=203
Step-by-step explanation:
x= 32
Answer:
- 23
- 6
- 25
- 30
- 11
Step-by-step explanation:
For these problems, you need to know that the sum of segment lengths on a line is the length of the line. You also need to know that a midpoint divides a segment into two equal parts.
1. JH = JI +IH = 12 + 11
JH = 23
__
2. KJ = JI
6 = JI
__
3. The distance between two points on a number line is found by subtracting the number at the left end from the number on the right end.
SU = U - S = 10 -(-15)
SU = 25
__
4. TV = V - T = 25 -(-5)
TV = 30
__
5. RS +ST = RT
RS + 2 = 13
RS = 11
