So use half the surface area formula: SA=2πr^2 and plug in what you already know
since you don't know the radius yet, solve for it using the circumference
C=2πr
514.96=3.14(2)r
82=r
SA=2π(82)^2
SA=6.28(6724)
SA=42,226.72
so your answer is 42,226.72 yards squared
Solar energy plants take up a lot of land space and can destroy animals habitats. Geothermal is bad because it gives of CO2 which can lead to global warming. Finally, wind power plants (turbines) also take up a lot of space and can destroy animals habitats. They can even be put in the water and destroy marine life.
Answer:
√1.45 = 1.2041594578792
Explanation:
Step 1:
Divide the number (1.45) by 2 to get the first guess for the square root .
Step 2:
Divide 1.45 by the previous result. d = 1.45/0.725 = 2.
Average this value (d) with that of step 1: (2 + 0.725)/2 = 1.3625
previous value = 0.725 - 1.3625 = 0.6375.
0.6375 > 0.001
Now we repeat the step
Step 3:
Divide 1.45 by the previous result. d = 1.45/1.3625 = 1.0642201835.
Average this value (d) with that of step 2: (1.0642201835 + 1.3625)/2 = 1.2133600918
Error = new guess - previous value = 1.3625 - 1.2133600918 = 0.1491399082.
0.1491399082 > 0.001.
Step 4:
Divide 1.45 by the previous result. d = 1.45/1.2133600918 = 1.1950285903.
Average this value (d) with that of step 3: (1.1950285903 + 1.2133600918)/2 = 1.2041943411 (new guess).
Error = new guess - previous value = 1.2133600918 - 1.2041943411 = 0.0091657507.
0.0091657507 > 0.001.
Step 5:
Divide 1.45 by the previous result. d = 1.45/1.2041943411 = 1.2041245757.
Average this value (d) with that of step 4: (1.2041245757 + 1.2041943411)/2 = 1.2041594584
- previous value = 1.2041943411 - 1.2041594584 = 0.0000348827.
0.0000348827 <= 0.001. accuracy, we stop the iterations and use 1.2041594584 as the square root.
The correct answer is Humans and chimpanzees have DNA that is very similar because they both evolved from a common ancestor.
Explanation:
Both humans and chimpanzees are primates; this means both species belong to the same biological order (rank in taxonomy). Moreover, humans and chimpanzees share most of their DNA (around 99%). This indicates the two species are related and they evolved from the same ancestor. This implies a primate that existed million years ago (common ancestor) was the origin of these two species and due to this common ancestor they share most of their DNA; however, as both species changed separately the remaining DNA is different and this makes both species look and be different. According to this, the correct statement about the evolution of primates is "Humans and chimpanzees have DNA that is very similar because they both evolved from a common ancestor."
