Answer:
Maths keeps one mentally active. The total surface of a hemisphere = 3(pi)r^2. So if the radius = 10 cm, then the TSA = 3(pi)r^2 = 300(pi) = 942.8571429 sq cm.
Step-by-step explanation:

Answer: 8x10 to the power of 9 = 80000000000
2x10 to the power of 3 = 2000
And I don’t know understand why you put 1x10 to the power of 2
But 1x10 to the power of 2 =100
Step-by-step explanation: Is this kind of answer you want hope this help
i = 3c
i = c + 14
set both equations equal to each-other, we can
solve for c, we must.
3c = c + 14
subtract c from both sides, we must.
2c = 14
divide both sides by 2, we must.
c = 7
