Answer:
725.71 cm
Step-by-step explanation:
Using the attached diagram :
Diameter of inner circle = 26
Radius of inner circle = 26/2 = 13
Radius of entire circle = 13 + 7 = 20
The Area of a circle = πr²
Area of inner circle = π13² = 169π
Area of entire circle = π20² = 400π
Area of shaded portion :
Area of entire circle - Area of inner circle
400π - 169π = 231π = 725.71 cm
Multiply 6 by 1/2 to get 3
Ow you have :
3( h + 1) = 18
Distribute the 3:
3h + 3 = 18
Subtract 3 from both sides:
3h = 15
Divide both sides by 3:
H = 5
Answer:
Undefined
Step-by-step explanation:
The formula for slope is [ y2-y1/x2-x1 ].
0-(-3)/1-1
3/0
Since the denominator is 0, the slope is undefined.
Best of Luck!
Step-by-step explanation:
Pythagoras : the lengths are the hypotenuses of the right-angled triangles created by the differences of the x and the y coordinates.
so,
AB² = (0 - -3)² + (2 - 8)² = 3² + (-6)² = 9 + 36 = 45
AB = sqrt(45) ≈ 6.7
CD² = (-2 - 0)² + (2 - -4)² = (-2)² + 6² = 4 + 36 = 40
CD = sqrt(40) ≈ 6.3
