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

The mass of an electron is approximately 9.11 × 10 -28 grams. Find the mass of 401,000,000 electrons. 3.65311 × 10-19 grams 3.65
NNADVOKAT [17]

Answer:

Total\ Mass = 3.65311 * 10^{-19} grams

Step-by-step explanation:

Given

Mass = 9.11 * 10^{-28}g

Required

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:

Total\ Mass = 401,000,000 * 9.11 * 10^{-28}

Total\ Mass = 3653110000 * 10^{-28}

Express 3653110000 as a standard form

Total\ Mass = 3.65311 * 10^9 * 10^{-28}

Apply law of indices:

Total\ Mass = 3.65311 * 10^{9-28}

Total\ Mass = 3.65311 * 10^{-19}

Hence, the mass of 401000000 electrons is 3.65311 * 10^{-19}\ grams
