Answer:
314 m²
Step-by-step explanation:
the surface area of a sphere (As) is
As = 4×pi×r²
our radius r (half of the diameter) here is 5m.
As = 4×3.14×5² = 4×3.14×25 = 100×3.14 = 314 m²
1/6 - 1/8
LCD: ?
Lowest common denominator is 24, therefore
4/24 - 3/24 = 1/24
Answer is 1/24
Analyze problem
since the distance is the same, we will not need to do any solving in that part
so, the average of 80 and 100 is
(80+100)/2
which is 90
so, 90 miles per hour
