Answer 1

Answer:

option C

Explanation:

For Naomi's rectangular prism:

⇒ Length × Width × Height

⇒ 5 × 14 × 2

⇒ 140 cm³

For Ben's triangular prism:

⇒ 1/2 × Base × Height × Length

⇒ 1/2 × 5 × 4 × 14

⇒ 140 cm³

The prism's have the same volume.

Answer 2

Answer: Choice C

===========================================================

Explanation:

The volume of the rectangular block is:

V = L*W*H = 5*14*2 = 70*2 = 140 cubic cm.

Now move onto the triangular prism.

The triangular face has a base of 5 cm and height of 4, so the area of this face is

A = base*height/2 = 5*4/2 = 20/2 = 10 square cm

Multiplying this with the depth of the prism tells us the volume is

V = (area of the base)*(depth) = (10 sq cm)*(14 cm) = 140 cubic cm

Therefore, the prisms have the same volume.

What is the area and circumference of the circle (3.14 for pi)

Answers

We will use the proper formula and solve.

    -> A diameter of 48 / 2 = 24 feet as our radius

   Area:

A = πr²

A = (3.14)(24)²

A = 1,808.64 ft²

      The circle has an area of about 1,808.64 ft²

   Circumference:

C = 2πr

C = 2(3.14)(24)

C = 150.72 ft

      The circle has a circumference of about 150.72 ft

Answer:

Circumference = 150.72

Area = 1808.64

Which point on the number line represents the approximate volume of a cone with a radius of 3 units and a height of 4 units? Use 3.14 for π.

Answers

Answer:

The point closest to the number 40

Step-by-step explanation:

To find volume of cone:

[tex]V=\pi r^{2} \frac{h}{3}[/tex]

(but in this case we will be substituting [tex]\pi[/tex] for it approximation: 3.14)

So our new equation is [tex]V= 3.14r^{2} \frac{h}{3}[/tex]

All right, let's get to work now.

Following the order of operations our first step would be: [tex]3^{2}[/tex] or 3x3 wich is 9Next step would be 3.14x9, which is 28.26After that we would solve [tex]\frac{4}{3}[/tex], which is 1.3 repeating but we can round to the nearest tenth and get 1.3Next we would multiply 28.26 by 1.3 which is 36.73800

We would next round to the nearest whole and our final answer is: 37
