A sphere has a radius of 25 ft . Find the surface area S of the sphere

Step-by-step explanation:

The appropriate formula here is

S = 4·π·r²

and with r = 25 ft, we obtain:

S = 4·π · (25 ft)²  = 4 · π · 625 ft²

its d. the first coordintaes are 10,32

step-by-step explanation:

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
