Answer:
254 4/7 or 254.34 ft² (it depends on which method you use.)
Step-by-step explanation:
To find the area of a circle, the formula is πr².
I'll use both 22/7 and 3.14 as pi, so I'll end up with two different answers. Just choose the more reliable one.
22/7 version:
22/7 * 9^2
22/7 * 81/1
1782/7
254 4/7 ft²
3.14 version:
3.14 * 9^2
3.14 * 81
314 - (3.14 * 19)
314 - 62.8 + 3.14
251.2 + 3.14
254.34 ft²
As I said, I ended up with two different answers. You also had said not to round my answer, so the 22/7 version has a mixed number.
The answer is C though.
I am sure of it from what i remember whenever i was in 9th
Answer:
2
A)-7y^3-3y^2-2y-8
B)-7x^3y^3-12x^2y^2-xy
C)2xy^3+3xy^2-5
3
A)14x^2
B)15a^2+30ab
Step-by-step explanation:
I would say false because even tho the angles could be in the same circle, each angle could be a different size.
Hope this helped :)
