The function h(x)=x^2+3 and g(x)=x^2-6 if g(x)=h(x)+k what is the value of k

hello : k = - 9

Step-by-step explanation:

h(x) =x²+3      and   g(x) = x² - 6(*)

g(x) = x² +3 + k(**)

by (*) and (**) : 3+k = -6

3+k - 3 = - 6 - 3

k = - 9

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
