The easiest way is to show him the formula for the area of a sphere:
Area = 4 π (radius)²
That's a good thing to discuss, because it's a good thing to remember,
and discussing it will help him remember it.
The important part to look at is the part where it says " (radius)² " .
That tells you that if you multiply the radius by (Anything), then
the area is multiplied by (Anything)² .
Since he multiplied the radius by 2, the area was multiplied by (2)² = 4 .
Answer:
$6 each
Step-by-step explanation:
the first 10 multiples of 3 are 3,6,9,12,15,18,21,24,27,30
3×2=6
6+6=12
35 because it is congruent to the other angle
Answer:
A. 9π/2km
Step-by-step explanation:
the length of the arc is
s= angle in radians* radius
the angle in radians
135 = 3π/4
therefore length of arc
s= (3π/4)*6 = 9π/2km
Answer:
<u>Simplify both sides of the equation</u>
