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
Answer:
(1,4,-4).
Step-by-step explanation:
Note: Consider A(2, 7,-5) and B (-3,-8, 0).
Section formula: If a point divides a line segment in m:n, then coordinates of that point are
It is given that C divides AB one fifth of the way from A to B. It means AC:AB=1:5
AC:CB=1:(5-1)=1:4
Using the above formula, we get
Therefore, the coordinates of C are (1,4,-4).
