ABC is the image of ABC after a rotation about the centre of rotation D.
Suppose that
you use a
compass to
draw a circle
with centre D,
and B is on the
circle. Which
other point
must be on the
circle? Explain.

y/x=18

step-by-step explanation:

a and c

step-by-step explanation:

triangle and cube

step-by-step explanation:

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to
