One hundred and ten thousand , four hundred and eleven
11000 + 400 +11
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

=100
∴r=10 cm
Hence, the answer is 10 cm.

To calculate probability take the events / the outcome.
3 grape sodas / total drinks
You will need to add all the drinks together to get the total drinks
(5 + 3 + 7 + 8 = 23)
3 / 23 is your probability
This ratio cannot be simplified into lowest terms
The percent increase is 25 %
<em><u>Solution:</u></em>
Given that we have to find the percent incraese
From 24 teachers to 30
The percent increase between two values is the difference between a final value and an initial value, expressed as a percentage of the initial value.
<em><u>The percent increase is given as:</u></em>

Here, initial value = 24 and final value = 30
<em><u>Substituting the values in above formula, we get</u></em>

Thus percent increase is 25 %
