Answer:
Diameter of cylinder = 12 cm
Step-by-step explanation:
Given:
Height of cylinder = 5 cm
Total surface area of cylinder = 3 x [Curved surface area of a cylinder]
Find:
Diameter of cylinder
Computation:
Total surface area of cylinder = 3 x [Curved surface area of a cylinder]
πr²h = 3[2πrh]
πr²h = 6πrh
Radius of cylinder = 6 cm
Diameter of cylinder = 2 x Radius of cylinder
Diameter of cylinder = 2 x 6
Diameter of cylinder = 12 cm
Answer:
Step-by-step explanation:
<u>Find the unit rate of the data in the table:</u>
- y = kx
- 2 = 6k
- k = 2/6
- k = 1/3
<u>The equation is:</u>
<u>Compare this with the others:</u>
- A. 3/11 < 1/3 = 3/9 ⇒ yes
- B. 2/5 > 1/3 = 2/6 ⇒ no
- C. 9/23 > 1/3 = 9/27 ⇒ no
- D. 4/13 < 1/3 = 4/12 ⇒ yes
- E. 3/8 > 1/3 = 3/9 ⇒ no
Answer:
33/40
Step-by-step explanation:
Find a common multiple or multiply each denominator so 1/5 *8 is 8/40 and 5/8*5 is 25/40, add them together to get 33/40 and simplify
