Question

I really need help plzzzzzzzzzzzzzzz
1. Sketch a regular hexagon ABCDEF is inscribed in a circle with centre O and radius r from a hard paper. Then find the formula for,
a. The side S
b.The perimeter P
c.The apothem a
d.The area A

2. construct a prism with base of a right is equilateral triangle with side 6 cm from your surrounding material and
a. Label lateral faces, lateral edges and bases
b. Find lateral surface area
c.Total surface area
d.volume

Answer 1

Answer:

the regular hexagon is inscribed in a circle of radius r. so it is inside the circle. by joining opposite sides of hexagon it forms 6 central angle at centre of each = 360 / 6

= 60°

and the 6 triangles are formed the two sides of each triangle are the radius of the circle and the equal the base angles of every triangle are equal

therefore ,Central angle = 60°

=>base angles =120 /2

=60°

therefore, the triangles are equilateral triangles

=> all sides are equal

therefore, all sides of each triangle is are perimeter of regular hexagon =6 s

sorry I knew the half of it
