try desmos u can type it in and it will show you but the answer is 1.333
Area of circle = πr²
= 64π
The cord will subtend a semicircle of diameter 8", radius 4". The area of this semicircle:
1/2 πr²
= 0.5 x 4² x π
= 8π
Area of larger region = area of circle - area of semicircle
= 64π - 8π
= 56π inch²
Answer:
35.4cm
Step-by-step explanation:
cubed root of 5= 1.7
16+16+1.7+1.7=35.4
Answer:
see explanation
Step-by-step explanation:
multiply both sides by 2 to eliminate the fraction
2d = 2
t + a
, that is
a + 2 t= 2d ( subtract 2t from both sides )
at² = 2d - 2 t= 2(d - t)
divide both sides by t²
a = 2(d - t) / t²
We calculate the sum of all interior angles using this formula 180(n-2) , n=number of sides
180(40-2)= 6840
6840 ÷ 40 = 171
