<span>No, it is never possible for a set of n vectors to span R^m where n is less than m. R^m has a dimension of m, so m vectors are required to span the space. In the case of three vectors in R^4, the three vectors span a space with a dimension of 3 and R^4 has a dimension of 4, so vectors can be found in R^4 which are outside the space of any three vectors.</span>
I don't know the answer sorry,
Answer:
508.3 m^2 to nearest tenth.
Step-by-step explanation:
Radius of the circular top = 12.5 / 2 = 6.25 m.
Surface area = area of curved side + 2 * area of the circular ends.
= 2 * 3.14 * 6.25 * 6.7 + 2 * 3.14 * 6.25^2
= 262.975 + 245.3125
= 508.2875
