Answer:
6580cm
Step-by-step explanation:
The answer is 6580cm because....
Step one First let's figure out what the smaller shape's volume is. To do so we need to multiply ( LxWxH ) so 6x5x? it does not list what the height is so we know it has the same height as the larger shape and it's height is 14cm so we will use 14cm. 6x5x14=420cm
Step two Now lets find the Volume of the larger shape. So lets do LxWxH so Lx?x14 it does not give us the length so we need to add up all of the numbers along the line. We got 7cm then 5 from the bottom of the smaller shape and 10cm. all ads up to 22cm so 20x22x14=6160
Finally we add up the following shapes Volume which are 6160+420=6580cm

A chef uses a circular pan with a 24-inch diameter to make a pizza. What is the area of pizza
RUDIKE [14]

Answer:

<u>The area of a pizza made in that circular pan is 452.39 inches²</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Diameter of the circular pan = 24 inches

Radius of the circular pan = 24/2 = 12 inches

2. What is the area of the pizza?

Let's use the formula of the area of a circle, this way:

Area = π * r²

Substituting with the real values, we have:

Area = 3.1416 * 12²

Area = 452.39 inches²

<u>The area of a pizza made in that circular pan is 452.39 inches²</u>

Two Dimensional Nets and Surface Area - Quiz - Level
Virty [35]

Answer:

18\ ft^2

Step-by-step explanation:

The complete question in the attached figure

we know that

The surface area of a cube is equal to the area of its 6 squares faces

so

The area of one square face is equal to

A=b^2

where

b is the length side of the square

we have

b=1\ ft

substitute

A=(1)^2=1\ ft^2 ---> area of one square face

Find the surface area of three cubes

Multiply the area of one square face by 6 (one cube has 6 faces) and then multiply the result by 3 (3 cubes)

so

SA=3[6(1)]=18\ ft^2
