Circumference = C = 28.26 cm
Area = A = 63.585 cm^2
Step-by-step explanation:
Given
Radius = r = 4.5 cm
Circumference:
Putting the values
Area:
Hence,
Circumference = C = 28.26 cm
Area = A = 63.585 cm^2

Answer:
x = 23
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp side/ hypotenuse
sin x = 3 / sqrt(58)
take the inverse sin of each side
sin ^-1 (sin x) = sin ^-1( 3 / sqrt(58))
x = sin ^-1( 3 / sqrt(58))
x=23.19859051
To the nearest degree
x = 23
Answer:
The answer is C. y+5=3(x-3)
Step-by-step explanation:
Point Slope Form is y - y1 = m (x-x1)
Since -5 is a negative, it becomes a + when y is subtracted by it, so y+5. 3 then converts x-3!
Moving 3 cm to the left would be "-3", then 7 to the right makes it "4" and 6 to the left makes it "-2", so it would be 2 centimeters behind 0, the total displacement is "2" (negative doesn't apply because you can't be -2 cm away from something)
Since the triangle is isosceles, the two legs have equal length. The coordinates of two vertices are given
P(3,3)
Q(3,1)
Assuming that PQ and QR are the legs of equal length, the distance between Q and R must be the same as the distance between P and Q
d = √[(3-3)² + (3-1)²
d = 2
Therefore, the coordinates of P is
(5,1)
