Best to look up the formula for the surface area of a sphere and then find it:
A = 4πr^2, where r is the radius of the sphere. Then,
A = 4π(15 in)^2 = 4(3.14)(225 in^2) = 2826 in^2 (answer)
This is represented by the formula given in the lower left.
Answer:
-54
Step-by-step explanation:
25x2+kx+4=0
50+kx+4=0
54+kx=0
54+-54=0
0=0
Convert the fractional part to a decimal, then add the result to the whole number part.
