Find the surface area of composite figure. use 3.14 for π. round to the nearest tenth

ExtremeBDS [4]

Combining of the two cylinders gives a composite figure that has the surface area of a solid cylinder of radius 7 mm and height 6 mm, such that the surface area of the figure is approximately 571.5 mm².

<h3>Which method can be used to find the surface area of the figure?</h3>

Radius of the inner cylinder, <em>r</em> = 3 mm

Radius of the outer cylinder, <em>R</em> = 7 mm

Height of the cylinders, <em>h</em> = 6 mm

Given that the inner cylinder exactly fits into the outer cylinder, we have;

The surface area of the composite figure is the surface area of the hollow outer cylinder + The area of the top and bottom of the inner cylinder.

Which gives;

The surface area of the composite figure, <em>A</em>, is the surface area of a solid cylinder, using the dimensions of the hollow outer cylinder.

A = 2•π•R² + 2•π•R•h

Which gives;

A = 2 × π × 7² + 2 × π × 7 × 6

Where, π = 3.14, we have;

A = 2 × 3.14 × 7² + 2 × 3.14 × 7 × 6 ≈ 571.5

The surface area of the composite figure, <em>A </em>≈ 571.5 mm²

A grocery store recieves a 180-pound crate containing six 10-pound bags of potatos and an unknown number of 5-pound bags of pota

Diano4ka-milaya [45]

Answer:

$60+5x = 180$

Step-by-step explanation:

Let the number of bags of potatoes be x.

We have been given that a grocery store receives a 180-pound crate containing six 10-pound bags of potatoes and an unknown number of 5-pound bags of potatoes.

The weight of 6 potato bags of 10 pound each will be $6\times 10=60$ pounds.

We can write an equation for the number of bags of potatoes by equating the weight of six 10-pound bags of potatoes and x 5-pound bags of potatoes with 180 pounds.

$6*10+5x = 180$

$60+5x = 180$

Therefore, the equation that represents the number of bags of potatoes in the crate is $60+5x = 180$ .

-6x+4y=-12 in slope intercept form

cricket20 [7]

Answer:

x= 2 /3 y+2

Step-by-step explanation:

Let's solve for x.

−6x+4y=−12

Step 1: Add -4y to both sides.

−6x+4y+−4y=−12+−4y

−6x=−4y−12

Step 2: Divide both sides by -6.

−6x /−6 = −4y−12 /−6 x= 2 /3 y

=x= 2 /3 y+2
