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:
2.25t
Step-by-step explanation:
Given function:
- 7.5% and 30t
- to find 7.5% of 30t
- t is just a variable
Multiply 7.5% with 0.01:
- ·
Multiply 0.075 by starting term:
- ·
Therefore, 7.5% of 30t would be 2.25t.
