Answer: Divide 2 by 6- 0.3 with a bar over the 3, Step-by-step explanation: 0.3 with a bar over the 3 is the decimal form of 2/6
Hope this can help you. I tried to solve each one out and I tried to write notes on how I got the equation and the answer. Message me if you can't read something, my handwriting tends to be messy :)
Curved surface area of a sphere =1256 cm
2
We know that, Curved surface area of a spehre =4πr
2
⟹1256=4×3.14×r
2
⟹r
2
=
4×3.14
1256
⟹r
2
=100
∴r=10 cm
Hence, the answer is 10 cm.
4186.66666666 volume of sphere
Answer:
65
Step-by-step explanation:
If the intent of the question is to estimate, I would say do so through rounding. 12.95 is basically 13 and 5.2 is basically 5. So 13 x 5 = 65 would be a good estimate.
This will be
570,000,000
- add 8 digits after the 5
