Answer:
B: 21.99
Step-by-step explanation:
recall that for a circle, circumference is given by:
circumference = 2π x radius
= π x diameter
we are given taht the diameter is 7 cm and π = 3.14
simply substitute these values into the formula for circumference:
circumference
= π x diameter
= 3.14 x 7
= 21.98
(the closest answer to this is B: 21.99)
Step 1) Look at the base
We can see that the base is a square, so most likely then this net is a pyramid.
Step 2) Look at the sides
We can see that there are 4 sides, and they are triangles.
By definition, a triangular pyramid only has 3 sides, which we know because it has 'triangle' in its name. But, the tetrahedron has 4 sides, which we know because it has the prefix 'tetra' in it, which means 4.
The correct answer is tetrahedron.
Hope this helps! :)
