The formula for the surface area of a cylinder is [tex]2\pi rh+2\pi r^{2}[/tex]. Using this, you can calculate that the cylinder's total surface area is 56[tex]\pi[/tex]. But, since Adrian only needs to find the surface area outside of the tire, I'm going to assume that you only need to apply [tex]2\pi rh[/tex] to your problem. Therefore, the answer is 24[tex]\pi[/tex] or 75.4 (rounded to the nearest tenth). I hope this helps!

The length of Ruben’s rectangular backyard is 10 meters more than the width. If the perimeter of the backyard is 220 meters, what is the length of the rectangular backyard?

Answers

Answer:

60

Step-by-step explanation:

given: length = 10m + width

perimeter = 220

find length of backyard

Solution

let us assume width = x

length = 10 + width

10 + x

perimeter of rectangular backyard = 2( length + width)

= 220 = 2 ( 10 + x + x )

= 220 = 2 ( 10 + 2x )

= 220 / 2 = 10 + 2x

= 110 - 10 = 2x

= 100/2 = x = 50

so, according to above solution and Q.

width = x = 50

length = 10 + width = 10 + x = 10 + 50 = 60

So the answer is 60

2 friends shared 48 pineapple equally among themselves. One of the friends sold all his pineapple each at $5.How much did he get from selling the pineapples?

Answers

Answer:

$120

Step-by-step explanation:

48 pineapples shared equally by 2 people.

48/2 = 24

Each friend got 24 pineapples.

24 × $5 = $120

Answer: $120

Answer: $120

Step-by-step explanation:

Step 1: Find how many 1 person gets (pineapples per person)

48 pineapples divided by 2 people= 48÷2= 24 pineapples each.

Step 2: Money made by 1 person

He has 24 pineapples to sell because that's how many he is supposed to receive. he sells all of them for $5 each, so the total money he makes is 5x24= $120

Checks:

120÷24= 5

the pineapples are 5 dollars each (this is correct).

Solving Algebraic EquationsRules

To solve, you must isolate the variable. This means moving the variable and it's coefficient to the other side of the equation with only the same variable on the same side with all the constants on the other side.

If you multiply, divide, add, subtract, square root, exponent both sides of the equation by the same value, that end value stays the same.

Terminology

Variable: Any letter than stands for a value than can be solved and change value. (i.e. x, y, z, a, etc.)

Coefficient: The number right before a variable (without being separated by an operator). It is a multiplication factor for a variable. Basically, it's just a way to express what you are multiplying a variable by.

If the coefficient is 1, it means [variable] * 1. 1[variable]

Q)

Subtract 23 on both sides.

29 - 23 = v + 23 - 23

v = 29
