A cone has a diameter of 8ft and height of 3ft. What’s the volume?

stepladder [879]

Step-by-step explanation:

1/3 πr²h

Given

diameter (d) = 8ft

radius (r) = d/2 = 8/2 = 4 ft

height (h) = 3 ft

Volume of cone

$\frac{1}{3} \times \pi {r}^{2} h$

$\frac{1}{3} \times 3.14 \times {4}^{2} \times 3$

$\frac{150.72}{3}$

=50.24 ft³

Find an equation of variation where y varies directly as x and y = 7 when x = 0.5 .

Alisiya [41]

Answer:

y = 14x

Step-by-step explanation:

Use the direct variation equation, y = kx

Plug in 7 as y and 0.5 as x, and solve for k:

y = kx

7 = k(0.5)

14 = k

Plug this into the equation:

y = kx

y = 14x

So, the equation of variation is y = 14x
