Answer:
25.13 cm³
Step-by-step explanation:
Volume of a cone or pyramid is:
V = ⅓ A h
where A is the area of the base and h is the height.
V = ⅓ π r² h
V = ⅓ π (2 cm)² (6 cm)
V = 8π cm³
V ≈ 25.13 cm³
The equation of the straight line is y = -1/6(x - 10) + 4
<h3>How to determine the line equation?</h3>
The equation is given as:
y = 2x + 6
Linear equations are represented as:
y = mx + c
Where:
Slope = m
So, we have:
m = 6
The slopes of perpendicular lines are represented as:
n = -1/m
So, we have:
n = -1/6
The equation is then represented as:
y = n(x - x1) + y1
This gives
y = -1/6(x - 10) + 4
Hence, the equation of the straight line is y = -1/6(x - 10) + 4

Answer:
32 : 12 is the second equivalent ratio. = 48 : 18 is the third equivalent ratio. Therefore, the three equivalent ratios of 8 : 3 are 16 : 6, 32 : 12 and 48 : 18
Answer:
a. dbc = 66, ABC = 132
b. abd = 52, dbc= 52
Step-by-step explanation:
just remember that bisects means that the angles on either side of the middle line are equal. so for a, dbc = abd and ABC = 2x 66
for b, abd and dbc are equal, so both of them are just 104 divide by two
