Surface area of a sphere is 4 times pi timers radius^2
aprox pi=3.14
so surface area=145,000,000
145,000,000=4 times 3.14 times rdaius^2
145,000,000=12.56 times radius^2
divide both sdies by 12.56
11544585.987=r^2
square root both sides
3397.73=radius
round to the hundreds
3397 rounded to the hundreds
3400
the answer is D 3,4000 km
The answer is C). no correlation
Which questions do you need help with ?
For the first rectangle, the answer is 4n+1.2.
Explanation:
The perimeter is all the side lengths added together. That means, for this rectangle, the perimeter would be n+n+0.6+n+n+0.6, which can be simplified to 4n+1.2.
For the second rectangle, the answer is 6n+0.2.
Explanation:
Again, the perimeter is all the side lengths added together. That means, for this rectangle, the perimeter would be n+0.1+2n+n+0.1+2n, which can be simplified to 6n+0.2.
