Answer:
be rewritten as a square of a sum
Step-by-step explanation:
Step-by-step explanation:
the total surface area is the sum of the individual areas.
we have the ground area : a 6×6 square. = 36 cm²
and we have 4 equal triangles.
the area of a triangle is baseline × height / 2.
which is for each of these triangles
6 × 12 / 2 = 3 × 12 = 36 cm²
so, the total surface area of the pyramid is
36 + 4×36 = 5×36 = 180 cm²
Answer:
12.22
Step-by-step explanation:
There are 360° in a full circle
The circumference of a circle is c = 2πr
----------------------------------
The lenght of the arc will be the portion of the circumferece included in the angle
l = (∅/360) * 2πr
plug in the knowns
l = (70/360) * 2π(10)
l ≈ 12.22
Answer:
Step-by-step explanation:
if two parallel lines are cut by a traversal, the alternate exterior angles are congruent. If two lines are cut by a traversal and the alternate exterior angles are congruent, the lines are parallel. Corresponding Angles: The name does not clearly describe the "location" of these angles
