Dinosaurs have been extinct for about 6.5 X 10 years, while Neanderthals have been extinct for about 30 x 109 years. About how many times longer have dinosaurs been extinct than Neanderthals?
1000 times longer
20,000 times longer
2000 times longer
O 10,000 times longer

1,000 times longer

Step-by-step explanation: Dino have been extinct for about 60 million years ago, and Neanderthals have been extinct for about 40,000 years.

60,000,000 divided by 40,000 is 1500 so 1000 times longer (sorry if im wrong i'm new)

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
