Answer: 6π
<u>Step-by-step explanation:</u>
Area of a circle is π r².
Area of a section of a circle is π r² × the section of the circle.
Given: r = 6, Ф = 60°
Answer:
yes, system have a solution
Step-by-step explanation:
Given data
linear equation = 6
unknown = 9
to find out
Will the system necessarily have a solution
solution
we multiply one non zero solution and we know that
A = 6 × 9 matrix
and n = 9
so dim (NulA) = 3
because we know (9-6) = 3
and rank of (A) = n - dim(NulA) = 9 - 3 = 6
so we say now here image of A i.e 6 dimensional subspace (A have 6 row)
so that Col (A) will be
so its mean Ax = b has solution when we have b
so we now say that yes, system have a solution
