Answer:
7 seconds
Step-by-step explanation:
The radius of a sphere-shaped balloon increases at a rate of 2 centimeters (cm) per second.
surface area of the completely inflated balloon is 784 cm²
SA=4r²
784= 4r²
784/4= r²
196 = r²
14cm = r
Yhe radius of the complete inflated balloon is 14cm
If the ball inflate at the rate of 2 cm per seconds
Then it took 14/2 = 7 seconds to inflate fully
The answer is: "64 cubic inches" ; or, write as: "64 in³ " .
_______________________________________________________
Explanation:
V = L * w * h ;
= (4 inches) * (4 inches) * (4 inches) ;
(since a "cube" has the same length, width, and height)
= (4*4*4) inches * inches * inches) ;
= 16 * 4 * inches³ ;
= 64 inches³ ; or, write as: "64 in³ " ; or, write as: "64 cubic inches" .
