I need help with this question, thank you. EXPLAIN.

Answers

Answer:

263.76

Step-by-step explanation:

It is 7 times 12 times 3.14. Then you round your answer

The formula for the volume of a cylinder is V=πr^2h. Which is volume equals pie * radius squared * height. pie = 3.14. radius is diameter/2, 3.5 in this case, then squared which is 3.5 * 3.5. And the height is 12. You take 3.14, 3.5^2, and 12 then multiply each term. So your substituted equation would be V=3.14(3.5^2)12.

This is how it would go:

V=3.14(3.5^2)12.
3.5^2 = 12.25.
- just squared 3.5, that equals 12.25

V=3.14(12.25)12
3.14 * 12.25 = 38.465
- pie times 12.25 equals 38.465

V=38.465(12)
38.465 * 12 = 461.58
- 38.465 * 12 = 461.58

V=461.58
- Your answer is 461.58 centimeters!!

The Surface area of hexagonal pyramid= 358.32 cm square

Formula of surface area of hexagonal pyramid= 3ab+3bs

            s= slant height
here a= 6.93cm
         b= 8cm
         s= 8cm*
* a^2 + b/2 ^2 = s^2
  6.93^2 + 4^2 = 8

The surface area of the hexagonal pyramid is,

⇒ Surface Area of Hexagonal Pyramid = 478.32 square units

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

In the diagram of the base of the hexagonal pyramid, all the triangles are the same.

Here, The slant height of the pyramid (s) = 13 cm

And, Base (b) = 8 cm

And, Apothem (a) = 6.93 cm

Now, We know that;

The surface area of the hexagonal pyramid is,

⇒ Surface Area of Hexagonal Pyramid = (3ab + 3bs) square units

After putting the values we get;

⇒ Surface Area of Hexagonal Pyramid = (3 × 6.93 × 8 + 3 × 8 × 13) square units

⇒ Surface Area of Hexagonal Pyramid = 478.32 square units

Thus, The surface area of the hexagonal pyramid is,

⇒ Surface Area of Hexagonal Pyramid = 478.32 square units
