Answer:
7
Step-by-step explanation:
The centroid divides the median in a 2:1 ratio. Therefore,
AD = 2DM
x + 3 = 2(2x - 1) Remove parentheses
x + 3 = 4x – 2 Add 2 to each side
x + 5 = 4x Subtract x from each side
3x = 5 Divide each side by 3
x = ⁵/₃
AM = AD + DM
= (x + 3) + (2x – 1)
= 3x + 2 Substitute the value of x
= 3 × ⁵/₃ + 2
= 5 + 2
= 7
Length of median AM = 7.
Answer:
A) 100pi cm^2
Step-by-step explanation:
area of a circle: r^2pi
radius=1/2diameter
diameter=20 cm
radius=10cm
10^2pi cm
100pi cm^2
The perimeter is 2.5+ 2.5+2+3.5= 10.5 ft
The area is equal 6. I used the equation A= a=b/2*h
