We know that
[surface area of sphere]=4πr²
[surface area of hemisphere]=2πr²
(sphere)
r=12 in
[surface area of sphere ]=4π12²--------> 576π in²
(hemisphere)
r=12 in[surface area of hemisphere ]=2π12²--------> 288π in²
[the ratio of the surface area of sphere to the surface area of hemisphere]
=576π/288π-------> 2
the answer is
the ratio is 2

Determine the mass of 401,000,000 electrons
To do this, we simply multiply the mass of 1 electron by the number of electrons.
This gives:


Express 3653110000 as a standard form

Apply law of indices:


Hence, the mass of 401000000 electrons is
