Let's rewrite the numbers correctly:
3.2 × 10 ^ 4
3.6 × 10 ^ 2
Now let's do the multiplication step by step:
Step 1:
The step Kevin made:
(3.2 * 3.6) * ((10 ^ 4) * (10 ^ 2))
11.52 * (10 ^ (4 + 2))
11.52 * 10 ^ 6
Step 2:
Rewrite the expression:
11.52 * 1000000
Step 3:
Roll the comma to the right:
11520000
Answer:
the next step that Kevin should apply to his solution is:
Step 2:
Rewrite the expression:
11.52 * 1000000
Step 3:
Roll the comma to the right:
11520000
area = PI x r^2
radius = 1/2 diameter
1/2 of 8 = 4
3.14 x 4^2 = 3.14 x 16 = 50.24 square inches ( answer may vary depending on what you use for PI. 3.14 is common)
Answer:
338.4Step-by-step explanation:
If you do 80 percent of 188, its 150.4. Then, you add 150.4 to 188. thats 338.4
Yes it can be guaranteed to get a sum of 7 once
