The answer is 43.6 your welcome 87.20 divided by two is 43.6.
The formula for surface area of a sphere: A = 4 pi r^2.
Since the radius is 30 m then A = 4pi30^2.
30^2 x 4 =3600
A=3600pi m
Answer:
2.05
Step-by-step explanation:
First, you would have to do 11x + 3x Since you're combining like terms.
Now your problem is 14x + 40 = -24
Now you would do 40 - -24 which is now 40+24 and equal to 64.
Now you divide 14 by 64 and you get 4.5
7.3 * 10^2= 730. Just move the decimal two laces to the right.
