The surface area of the regular hexagonal pyramid is SA = (1/2) pl + B where p is the perimeter of the base, l is the slant height of the pyramid, and B is the area of the base The area of a regular hexagon is 3 sh where s is the length of the side and h is the length of the apothem. So, SA = (1/2)(6)(12) (11) + 3(12)(6sqrt3) SA = 770 square meters
The answer is B, 770, if you have an questions please feel free to ask, i have done this test already i got 100, need help with other answer just send me, and i will answer right away :).
C = πd. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi. Plugging π into your calculator will give you its numerical value, which is a closer approximation of 3.14 or 22/7.
The radius is half as long as the diameter, so the diameter can be thought of as 2r. Keeping this in mind, you can write down the formula for finding the circumference of a circle given the radius: C = 2πr. In this formula, "r" represents the radius of the circle. Again, you can plug π into your calculator to get its numeral value, which is a closer approximation of 3.14.
