The surface of a sphere is given by the formula:
area=4πr²
Data:
r=30 m
area=4ππ(30 m)²=3600π m².
Answer: the area of this sphere is 3600π m².
What you put is correct because two negatives make a positive so it would be 5 + 7 making it the greatest value
Answer:
a. 2/3 ,4/6 ,6/9 ,4/12 ,10/15 ,12/18 .......
b. 2=4, 2=8, 2=16, 2=32, 2=64 .......
c. It goes in decending order from 100
Answer:
Angle BCA = 70
Angle CAB = 20
Step-by-step explanation:
Not sure what angle you meant, so I'll give you all of them <3
Angle BCA = 70 degrees, because If two angles form a line, they add up to 180. (110+x=180, x = 70)
Angle CAB = 20 degrees, because there are 180 degrees in a triangle, so 90+70+x=180, x = 20
Hope it helps <3
