Answer:
Part 1) The lateral area is
Part 2) The surface area is
so
lateral area = 210 cm2; surface area = 325.5 cm2
Step-by-step explanation:
Part 1) Find the lateral area of the regular hexagonal pyramid
The lateral area is equal to the area of its six triangular faces
so
we have
substitute
Part 2) Find the surface area of the regular hexagonal pyramid
The surface area is equal to the lateral area plus the area of the hexagonal base
so
where
B is the area of the hexagonal base
Find the area of the hexagonal base
The area of the regular hexagon is equal to the area of six equilateral triangles
we have
substitute
The surface area is equal to
You can do this by doing 1800 / 15 which is 120 and 1800 / 20 which is 90
Which means that the x intercept is 120 and the y intercept is 90.

Naming each number in word with the use of place value to name whole numbers: we have;
<em>4. Five hundred and twenty-five thousand, Six hundred minutes.</em>
<em>4. Five hundred and twenty-five thousand, Six hundred minutes.5. Two-million, six-hundresd and seventeen thousand, one-hundred and seventy six.</em>
<em>4. Five hundred and twenty-five thousand, Six hundred minutes.5. Two-million, six-hundresd and seventeen thousand, one-hundred and seventy six.6. Eighteen thousand, five-hundred and fourty-nine thousand dollars.</em>
Using place value to name whole numbers involves orderly naming the numbers from right to left from unit, tens, hundreds, thousands, ten thousands and so on.
Ultimately, the naming of the numbers is as done above.
