Best ResponseYou've already chosen the best response.0i see now do you know how to find the area of a regular octagon

Best ResponseYou've already chosen the best response.0area = length x length so from here you can work out what the answer might be

Best ResponseYou've already chosen the best response.0No, wouldn't it be 210 because 35*6=210?

Best ResponseYou've already chosen the best response.0If you increase the length by 6 then the area will increase by 6 squared

Best ResponseYou've already chosen the best response.0Is there a specific formula I'm supposed to do to solve this one?

Best ResponseYou've already chosen the best response.0@alekos I got 25.12 for some reason, but that's not an option.

Best ResponseYou've already chosen the best response.0yes there is a specific formula Area of a circle is pi x r^2 but in this case we only have part of a circle or a fraction of a circle. What do you think that fraction will be?

Liv1234

Best ResponseYou've already chosen the best response.0the fraction would be 1/2 since we have half a circle.

alekos

Best ResponseYou've already chosen the best response.0No we don't. Half a circle would be 180 degrees. We have 172 degrees

Best ResponseYou've already chosen the best response.0Ohh, I'm sorry that's right. So 172.

Liv1234

Best ResponseYou've already chosen the best response.0So, how would I calculate it?

alekos

Best ResponseYou've already chosen the best response.0and the fraction is 172/?

alekos

Best ResponseYou've already chosen the best response.0No. Whats the number of degrees of a full circle?

alekos

Best ResponseYou've already chosen the best response.0yes. so the fraction is ?

alekos

Best ResponseYou've already chosen the best response.0beautiful. so this is what you have to multiply by the area of the circle with radius 4

alekos

Best ResponseYou've already chosen the best response.0no. whats the area of a circle?

alekos

Best ResponseYou've already chosen the best response.0no. thats the number of degrees. Have you been taught the area formula?

Liv1234

Best ResponseYou've already chosen the best response.0We're trying to figure out the area, right? So how would I know the area?

alekos
 one year ago
Best ResponseYou've already chosen the best response.0Yes we are. I'm asking you if you know the Area formula of a full circle with radius r

alekos

Best ResponseYou've already chosen the best response.0OK. now we're getting somewhere So the area of the arc (172 deg) = (172/360)*pi*r^2
