ankoles [38]3 years ago
7 0

Answer:

1861.39 cm²

Step-by-step explanation:

Given:

d = 15 cm

radius (r) = ½(15) = 7.5 cm

Height = 32 cm

Surface area of a cylinder = 2πrh + 2πr²

Plug in the values

Surface area = 2*π*7.5*32 + 2*π*7.5²

= 1861.39 cm²

A cell phone company has a basic plan of $40 plus $0.45 for any minutes over 700. Before receiving his statement, John saw he wa
Darya [45]

Answer:

718\ min

Step-by-step explanation:

Let

x ----> the number of minutes

y ----> the total charge in dollars

we know that

For x>700 min

y=0.45x+40

so

For y=48.10

substitute

48.10=0.45x+40

Multiply by 100 both sides

4,810=45x+4,000 ----> equation without decimals

solve for x

45x=4,810-4,000\\45x=810\\x=18\ min

To find out the total minutes we need to sum

18\ min+700\ min=718\ min

What is the surface area of a cylinder that has the following measurements? area of each base: 50.24 ft2 area of lateral surface
irinina [24]

Answer:

TSA = 175.84 ft²

Step-by-step explanation:

We are given;

Lateral surface area; A_L = 75.36 ft²

Area of base; A_b = 50.24 ft²

Height of cylinder; h = 3ft

Formula for total surface area of Cylinder is;

TSA = 2πr² + 2πrh

Now, lateral surface area is given by the formula; A_L = 2πrh

Area of base is given by the formula;

A_b = πr²

Thus, let's apply these 2 formulas to the formula for total surface area;

TSA = 2(Area of base) + Lateral surface area

TSA = (2 * 50.24) + 75.36

TSA = 175.84 ft²

Answer:

$10

Step-by-step explanation:

The question made is How much did I have? This question is about the amount of money that you had before receiving the money from your mom, dad and aunt and uncle. This means that the answer is the $3 you had plus the other $7 you said you had. So, $3+$7=$10. You had $10.
