Answer:

B. $LA=2\pi rh$

Step-by-step explanation:

The lateral area of the right cylinder refers to the curved surface area.

The lateral area of the right cylinder does not include the two circular bases.

The lateral area is given by the formula;

$LA=2\pi rh$

The correct choice is B.

Fractions: three oil tankers together contain 37 5/7 litres of oil. If two tankers have 11 3/14 litres and 12 3/7 litres of oil.

ale4655 [162]

Step-by-step explanation:

It is given that, three oil tankers together contain 37 5/7 litres of oil.

Total volume of oil is $\dfrac{264}{7}\ L$

If two tankers have 11 3/14 litres and 12 3/7 litres of oil.

Oil in first tanker is $\dfrac{157}{14}\ L$

Oil in second tanker is $\dfrac{87}{7}\ L$

Oil in first and second tanker is :

$\dfrac{157}{14}\ L+\dfrac{87}{7}\ L=\dfrac{331}{14}\ L$

Noo, oil in the third tanker = total volume - (Oil in first tanker + second tanker )

$=\dfrac{264}{7}\ L-\dfrac{331}{14}\ L\\\\=\dfrac{197}{14}\ L$

Hence, this is the required solution.

4d + 5 >= 13 or 7d - 2 <12

vivado [14]

I'm guessing that the >= is a greater than or equal to sign, so the answer should be d>=2 and d<2, please tell me if I am wrong and I will do my best to correct it!

Point S is on line segment \overline{RT}

Semenov [28]

Answer:

RT = 20

Step-by-step explanation:

Point S is on line segment

R------------S------------T

RS + ST = RT

Given

ST=3x-8

RT=4x

RS=4x-7,

Step 1

We find x

4x - 7 + 3x - 8 = 4x

4x + 3x -7 - 8 = 4x

7x - 15 = 4x

7x - 4x = 15

3x = 15

x = 15/3

x = 5

Step 2

We find RT

RT = 4x

x = 5

RT = 4 × 5

RT = 20

The numerical length of RT is 20
