Triangle:
11 x 10 110
——— = ———-
2 2

= 55in

55 x 4 = 220, cause there’s 4 triangles.

Rectangles: (sides)
5.6 x 10 = 56

56 x 4 = 224

Square:
10 x 10 = 100

100 x 2 = 200

Entire surface area:
200 + 224 + 220
= 644

surface area is 644in.

A group of friends shared the cost of a printer. If John, Carl and Jason each paid $15, $25, and $112 respectively, then Carl pa
vfiekz [6]

The percent of the cost of the printer Carl paid is 16.45%

<h3>The total cost of printer</h3>

Since John, Carl and Jason each paid $15, $25, and $112 respectively, the total cost of the printer is T = $15 + $25 + $112 = $152

Since Carl paid $25, we need to find the percent of the total amount Carl paid.

<h3>Percent Carl paid</h3>

So, percent Carl paid = amount Carl paid/total cost × 100 %

Since amount Carl paid = $25 and total cost = $152,

Substituting the values of the variables into the equation, we have

percent Carl paid = amount Carl paid/total cost × 100 %

percent Carl paid = $25/$152 × 100 %

percent Carl paid = 0.1645 × 100 %

percent Carl paid = 16.45%

The percent of the cost of the printer Carl paid is 16.45%

6. Answer:

72.84

Step-by-step explanation:

To find the perimeter of the rectangle, just add the sides together except the one connected to the semicircle

12 + 15 + 15 = 42

The diameter of the semi circle is 12

πr + d = 6 * π + 12 ≈ 30.84

Add them together

42 + 30.85 = 72.84

7. Answer:

78.54

(78.5)

Step-by-step explanation:

The shape is a circle

Radius is 5

Diameter is 10  (diameter is always double of the radius)

π * r^2 = π * 25 cm^2 = 78.54 cm^2

8. Answer:

50.27

Step-by-step explanation:

The shape is a circle

Radius is 4

Diameter is 8  (diameter is always double of the radius)

π * r^2 = π * 16 ft^2 = 50.27 ft^2

(16 = 8 * 2)
