Answer:
circumference is 50.24cm
Step-by-step explanation:
π
= 200.96
r = 
= 
=8
Circumference = 2πr = 2 x.3.14.x 8 = 50.24
The surface area of the square pyramid net consisting of a square and four triangles is 380 sq. cm
<h3>How to find the surface area of a figure?</h3>
The surface area of a square pyramid is equal to the sum of the ara of the base square and the four triangle.
<h3>Find the area of the square base</h3>
Area of the base = 10cm * 10cm
Base area = 100 sq,cm
Find the area of a triangle
Area of triangle = 0.5 * 10 * 14
Area of a triangle = 70 square cm
Area of 4 triangles = 4(70) = 280 sq.cm
<h3>Determine the surface area</h3>
SA = 100 + 280
SA = 380 sq. cm
Hence the surface area of the square pyramid net consisting of a square and four triangles is 380 sq. cm
