Hi there!!!
So using this rule:
Area = base * height
20ft * 15ft = 300ft^2
↑ ↑
base height
HOPE IT HELPS U!!!!!!!!!
THE ANSWER IS 300 FT^2

Answer:
x^ 3 -6
Step-by-step explanation:
x^ 3- 6
cubed x first. then subtract 6 from that
35 é divisível por 5 e 7
5 e 7 são números primos, logo, 35 pode ser escrito...
5*7, 7*5, 35*1

- First find the area of the whole circle
The equation is :
πr^2
Substitute the radius in:
π(5)^2
Solve:
Area of full circle = 25π
(Note : leave this answer in terms of 'pi' so it is easier to handle
Next, find the area of the sector
The equation for this is:
(angle/360) x πr^2
Substitute the values in:
(80/360) x π(5)^2
Solve :
Area of sector = (50/9)π
Now, find the area of the triangle:
1/2 absinC
Substitute the values in:
1/2(5)(5) x sin(80) = 12.31009691
Subtract this answer from the area of the sector
Answer = 5.14319607
Subtract this from the area of the whole circle
Answer = 73.39662073
To the nearest tenth, that would be 73.4 cm^2
Have A Nice Day ❤
