which math problem?? There is many on the picture
The formula you use to find the surface area of a sphere is A=4 π r^2
4×π = 12.5663706143
r = 4
4^2 = 16
12.5663706143 × 16 = 201.061929829
Final answer: the surface area is about 201 ft.
Answer:
376 square centimeters
Step-by-step explanation:
When doubled, the new length is 5*2=10 cm, new width is 4*2=8 cm, and new height is 3*2=6 cm.
The surface area of a rectangular prism is given by : 
Where l is length, w is width, and h is height
Plugging in the new values we get:

The surface area of the enlarged prism = 376 cm^2
