B----->
C----->
we know that
Point A-------> Multiply numerator and denominator by
Point B-------> Multiply numerator and denominator by
Point C-------> Multiply numerator and denominator by
Find the distance Point A to Point C
Find the distance Point B to Point C
therefore
Point B is closer to Point C
is closer to
the answer is
is closer to
Answer:
Step-by-step explanation:
1. You must apply the following formula for calculate the total surface area the regular pyramid:
Where p is the perimeter of the base, l is the slant height and B is the area of the base.
2. The perimeter is, where s is the side length:
3. The faces are isosceles traingles. So, to find the slant height you can divide one base into two equal right triangles and calculate the slant height with Pythagorean Theorem:
4. The base is equal to any face, then both have equal areas. As previously you divide one base into two equal righ triangle to find the slant height, you can calcualte the area of one right triangle and multply it by 2 to calculate B:
Finally substitute values:
