What is the total surface area of the pyramid?

Right Regular Pyramid Surface Area = (½ * Perimeter of Base * Slant Height) + Base AreaArea of a polygon = # sides * side^2 / 4 * tan(180 / #sides)Area = 6 * 9 / [4 * tan(30)]
Area = 54 / [4 * 0.57735]

Hexagon Area= 23.38 square meters

Lateral Area = (½ * Perimeter of Base * Slant Height)

Lateral Area = (.5* 6*3 * 6.54)

Lateral Area = .5* 6*3 * 6.54

Lateral Area = 58.86 square meters
TOTAL Area = 23.38 + 58.86 =82.24 square meters
Answer is D

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !
