Answer:
4.2×10to the 6th or 4,200,000
Step-by-step explanation:
First you have to know that you are multiplying these two numbers. When you multiply exponents like there you add the matissa's (6&7) and add the exponents.
6×10to the 2 * 7×10to the 3rd
42 × 10to the 2+3
42×10to the 5th
Something else you need to know is your matissa cant be higher than 10
So:
4.2 × 10to the 6th is your answer
The first circle is approximately 44 times greater than the second cirle
Radius = 110 mm
110² = 10,000 mm² = Area
Radius = 15 mm
15² = 225 mm² = Area
Hope this helps!
