Answer:
22.2 ft²
Step-by-step explanation:
The area (A) of a sector is calculated as
A = area of circle × fraction of circle
= πr² × 
= π × 7.13² × 
= 
≈ 22.2 ft² ( nearest tenth )
This is true. If you count the number of lbs, you get 16 and if you count the number of dollars in the same length, you get $4.
(4xy - 3z)²
(4xy - 3z)(4xy - 3z)
4xy(4xy - 3z) - 3z(4xy - 3z)
16x²y² - 12xyz -12xyz + 9z²
16x²y² - 24xyz + 9z², a perfect square trinomial.
The answer is 11 my friend :)
Answer:
AB = 3√5
Explanation: You can use
a^2 + b^2 = c^2 formula.
6^2 + b^2 = 9^2.
36 + b^2 = 81.
81 - 36 = 45
√45 = 3√5
