Answer:
314 m²
Step-by-step explanation:
the formula for the surface area of a sphere (As) is
As = 4×pi×r²
the radius r (half of the diameter) is clearly indicated as 5m.
so, As = 4×3.14×5² = 4×3.14×25
I don't even need a calculator for this, as 4×25 = 100
so, As = 100×3.14 = 314
(you know, when multiplying by 10, the decimal point moves right one position. multiply by 100 it moves 2 positions, and so on).
Answer:
(-2, -6)
Step-by-step explanation:
Slope: 1
we know that
For a spherical planet of radius r, the volume V and the surface area SA is equal to

The
ratio of these two quantities may be written as

we know


therefore
the answer is

Answer:
There would be $2,120
Step-by-step explanation:
First figure out what 3% of 2000 is which is 60. Multiply the 60 by 2 to get 120 then add 120 to 2000
Mean
add up numbers and divide by how many there are
(1+1+5+3+6+6)/7=3 and 2/3
