Answer:
Step-by-step explanation:
Remark
Area of an entire circle = pi * r^2
Area of a sector = angle / 360 * pi * r^2
Givens
angle = 140
radius = 8
Solution
Area = (140/360) * 3.14 * 8^2
Area =0.3889 * 3.14 * 64
Area = 78.15
Answer:
45°
Step-by-step explanation:
The angles of any triangle add up to 180 degrees
add the two known angles: 47+88=135
then subtract the sum from 180 to get answer: 180-135=45
Answer:
x = -0.24 or 3.73
Step-by-step explanation:
(There's supposed to be a ± between '-b' and the square root)
+ 4x + 1 ( )
a = -1 ( there's no number before so its 1 )
b = 4
c = 1
Substitute into the quadratic equation.
( the is just the multiplication sign )
=
= -0.24 [OR] = 3.73
( The answers are to 2 decimal places )
