Work out the surface area of this sphere 2.6cm

A = 27.04π cm²

Step-by-step explanation:

The surface area of a sphere of radius r is A = 4πr²

If the radius, r, is 2.6 cm, then the surface area here is A = 4π(2.6 cm)², or

A = 4π(6 .76 cm²) or

A = 27.04π cm²

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
