If there is a direct proportion between the price (y) and number of board games (2), which equation represents the
situation?
y = 75.2
By = 52

essay on kim jong un

Answers

Answer:

Step-by-step explanation:

From late 2010, Kim Jong-un was viewed as successor to the leadership of North Korea. Following the elder Kim's death in December 2011, state television announced him as the "Great Successor". Kim holds the titles of General Secretary of the Workers' Party of Korea,[7] Chairman of the Central Military Commission, and President of the State Affairs Commission. He is also a member of the Presidium of the Politburo of the Workers' Party of Korea, the highest decision-making body. In July 2012, Kim was promoted to the highest rank of Marshal in the Korean People's Army, consolidating his position as Supreme Commander of the Armed Forces. North Korean state media often refers to him as "the Marshal" or "Dear Respected Leader". He has promoted the policy of byungjin, similar to Kim Il-Sung's policy from the 1960s, referring to the simultaneous development of both the economy and the country's nuclear weapons program.

One equalion for finding the volume of a cylinder is V=Bh, where B represents the area of the base of the cylinder and h represents the height of the cylinder. Which expression could be used to find the volume of the cylinder in cubic meters ?​

Answers

Answer:

we have

diameter {d}=6.8m

radius (r)=3.4m

height]h}=8.5

now

volume of cylinder=πr²h=π([6.8]/2)²×8.5=

π(3.4)²(8.5) is your answer

Step-by-step explanation:

Diameter of the cylinder=6.8m

Radius=Diameter/2=6.8/2=3.4

We know that

[tex]\boxed{\sf Volume=\pi r^2h}[/tex]

[tex]\\ \tt \mapsto \:Volume_{(Cylinder)}=\pi(3.4)^2\times 8.5 units^3[/tex]

Hence option B is correct
