Using your value of a, the answer is 4x3x7x7 square metres. More accurate to use the correct value of a, which is pi (ie nearer to 3.142)
588.2 m2
Surface area of a sphere: A = 4πr2So, surface area = 4pi52
0.5m-1
Perhaps if you read the question properly, you would not have to ask the question!
No.there can be electric field on the Gaussian surface even if the charge enclosed by it is zero.However ,net flux will be zero through the surface.
288m2
Surface area equals 864cm2
Surface area of a sphere: A = 4πr2So, surface area = 4pi52
0.6 m-1 is the ratio of surface area to volume for a sphere.
0.4 m-1 is the ration of surface area 588m2 to volume 1372m3 for a sphere.

Length times width (of the cooking surface) equals the area you desire.
As an object falls towards the Earth's surface, its velocity increases due to the acceleration caused by gravity. Near the surface, the object will reach a terminal velocity where the force of air resistance equals the force of gravity, causing the object to fall at a constant speed.
The surface area of a sphere if its diameter is 9.65 cm equals 292.6cm2
127.5
