The formula to find the surface area of a sphere is A=4(3.14)r². So if you plug in the data you would get,
A=4(3.14)4²
A=(12.56) (16)
A=200.96
You mught want to check over it so you will be able to solve it for yourself the next time you have this question.
The last one is correct because 60+35+35+35=165
55+55+55=165
Answer:
1. A sound wave in air has a frequency of 262 Hz and travels at a speed of 330 m/s.

Answer:
(-6,-4)
Step-by-step explanation:
So there actually is really easy way to solve this problem(that many people will never teach you for some weird reason).
Find difference between two points first in x and y direction.
X difference = (-3 - (-8)) = 5
Y difference = (-1 - (-6)) = 5
Multiply 2/5 to each difference
X difference 5 * 2/5 = 2
y difference 5* 2/5 = 2
just add the two number to First point(point A)
-8 + 2 = -6
-6 + 2 = -4
(-6,-4)
