I haven't done this in a while, so I am very sorry if it is wrong, but I believe you take the angle measure of the part of the circle you need and put it over 360 then multiply by the formula for the area of a circle.

FURTHER ASK THIS QUESTION, THIS IS A STATEMENT
Step-by-step explanation:
There are 23 sharks and 7 octopi in the aquarium
- Let the number of sharks in the aquarium be x
- Let the number of octopi in the tank be y
If the total number of animals in the tank is 30, therefore;
- x + y = 30 ....................... 1
If the total number of legs in the tank is 171 with starfish having 5 legs and Octopus having 8 legs, the required expression will be:
- 5x + 8y = 171 ................ 2
From equation 1, x = 30 - y ................... 3
Substitute equation 3 into 2 to have:
5(30-y) + 8y = 171
150 - 5y + 8y = 171
3y = 171 - 150
3y = 21
y = 7
Recall that x = 30 - y
x = 30 - 7
x = 23
Hence there are 23 sharks and 7 octopi in the aquarium
