The diameter is two times the radius.
2 * 1 = 2
So the diameter is 2 yards.
Answer:
x = 4.
Step-by-step explanation:
These are exterior alternate angles which are congruent.
So 21x + 6 = 90
21x = 84
x = 4.
A cone because it is a circle when cut in half or anyway you cut it
6 for the two bases = 12
6 x 2 = 12 for the 4 faces = 48
48+12 = 60 cm^2
