Answer:
49,400,000
Step-by-step explanation:
(2.6*10^5)(1.9*10^2)
Apply exponent rule
=2.6*1.9*10^5+2
Add the numbers: 5+2=7
=2.6*1.9*10^7
Multiply the numbers: 2.6*1.9= 4.94
10^7*4.94
10^7=10,000,000
=10,000,000*4.94
Multiply the numbers: 4.94*10000000=49,400,000
=49,400,000
Thanks for letting me help!!
Area = πr² ⇒
81π = πr² ⇒ 81 = r² ⇒ r = √81 = 9 in
<span>Circumference = 2</span>πr = 2*9*π = 18π in
