The volume V of a cone with radius r is one-third the area of the base B times the height h.
so,
The answer is 57.3248408
Answer:
28+104 = 132cm^2
Step-by-step explanation:
We can find the area of this figure by breaking it into two separate pieces. The top is a rectangle and the bottom is a trapezoid.
A rectangle = l*w = 7*4 = 28 cm^2
A trapezoid = 1/2 (b1+b2) *h = 1/2 (19+7) *8 = 1/2 (26)*8 =104 cm^2
Add these areas together
28+104 = 132cm^2

Answer:
628.3 cm
Step-by-step explanation:
The window has a semicircle shape = half of a circle
Perimeter of the window = ½(πr²)
Radius (r) = 20 cm
Plug in the value
Perimeter of the window = ½(π*20²)
= ½(π*400)
Perimeter of the window = 628.31853 ≈ 628.3 cm (nearest tenth)
Answer:
1/2
Step-by-step explanation:
First we need to isolate -6y by subtracting 3x from both sides
-6y = 18 - 3x
Then we should divide everything by -6 to get 1y
y = -3 + 1/2x
Now we can put our equation into slope intercept form
y = 1/2x - 3
The slope is m, which is 1/2, and because all parallel lines have the same slope, the slope of our parallel line is also 1/2
