A square pyramid has base area 64 square centimeters. The surface area of this pyramid is 224 square centimeters. Find the height (h) to the nearest tenth of a centimeter. Pyramid height=cm.

Step-by-step explanation:

The side of the square base is:

The formula for the surface area of the pyramid is:

The height is cleared in the previous expression:

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
