The formula in computing the area of the circle is:
A = pi (r)^2
Where r = the radius of the circle
Since you are only given the diameter of the circle, you
have to solve for its radius. The radius of the circle is half its diameter. Therefore,
the radius of the circle is 5 (10/2).
Now, you substitute the measurements to the formula:
A = 3.14 (5)^2
A = 3.14 (25)
A = 78.5 sq. units
Answer:
0=7
Step-by-step explanation:
Distribute
4−5=2(2+1)
4−5=4+2
Add 5 to both sides of the equation
4 − 5 = 4 + 2
4 − 5 + 5 = 4 + 2 + 5
Simplify Add the numbers
Add the numbers
4 = 4 + 7
Result
0=7
Answer:
8.39 meters
Step-by-step explanation:
The angle is opposite the side of interest of the right triangle representing the geometry. The adjacent side is known, so the tangent function can be useful.
Tan = Opposite/Adjacent
tan(40°) = width/(10 m) . . . . . filling in given values
(10 m)·tan(40°) = width ≈ 8.390996 m ≈ 8.39 m
The width of the river is about 8.39 meters.
Answer:
Step-by-step explanation:
Endpoints of the segment line:
H ( 6, 4 ) and K ( 2, 8 ):
x 1 = 6, x 2 = 2;
y 1 = 4, y 2 = 8:
x m = ( 6 + 2 ) / 2 = 8 / 2 = 4
y m = ( 4 + 8 ) / 2 = 12 / 2 = 6
