Sive a parametric description of the form $r(u,v)=($:$x(u,v),y(u,v),z(u,v))$ for the following surface.

The cap of the sphere $x^2{y}^2{z}^2=49,$ for $\frac{7\sqrt[\phantom{2}]{3}}{2}z7$

Select the correct choice below and fill in the answer boxes to complete your choice.

Type any angle measures in radians. Use angle measures greater than or equal to $0$ and less than Type exact answers in terms of $)$

A$.r(u,v)=($:$7cosu,7sinu,v$:$)$ for $$ sus $$ and $v$

B$.r(u,v)=($:$7cosusinv,7sinusinv,7sinv$:$)$ for $0u2x$ and $0v\frac{}{6}$

$$

$$

$\frac{x}{6}$

C$.r(u,v)=(49cosu,49sinu,v)$ for $,u,$ and $,v$

D$.r(u,v)=($:$7sinucosv,7sinusinv,7cosu$:$)$ for $$ sus $$ and $v$
