the radius of the distance between the middle point of the circle and the outside, we have the diameter which is 6 so the radius will be 3

slant height is

$\sqrt{r^2+h^2}$

h is 4.7 and r is 3

$\sqrt{3^2+4.71^2} \\5.58427$

slant height is 5.58427

lateral surface area

$\pi r\sqrt{h^2+r^2}$

$\pi (3)\sqrt{4.71^2+3^2} \\52.63053$

lateral surface area is 52.63053

total surface area

$\pi r(r+\sqrt{h^2+r^2})$

$\pi 3(3+\sqrt{4.71^2+3^2})$

$80.90486$

total surface area is 80.90486

wind turbines generate large amounts of electricity from wind energy. the blades on a wind turbine can revolve 22 times per minu

lesya [120]

Answer:

1320 times

Step-by-step explanation:

Time = 1 h × (60 min/1 h) = 60 min

Revolutions = 60 min × (22 rev/1 min) = 1320 rev

The blades revolve 1320 times per hour.

Hi my lil bunny!

❧⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯☙

Let's solve your equation step-by-step.

$\frac{1}{4} x^2+5=0$

For this equation: $a=0.25, b=0, c=5$

$0.25x^2 + 0x + 5 = 0$

Step 1: Use quadratic formula with $a=0.25, b=0, c=5.$

$x = \frac{-b ± \sqrt{b^2 - 4ac} }{2a}$

$x = \frac{-(0) ± \sqrt{(0)^2 -4 (0.25) (5) } }{2(0.25)}$

$x = \frac{0 ± \sqrt{-5} }{0.5}$

Answer : No Real Solutions.

Answer:

? = 4.28

Step-by-step explanation:

We know that tan theta = opp side / adjacent side

tan 35 = 3 / ?

Multiply each side by ?

? tan 35 = 3

Divide each side by tan 35

? = 3/tan 35

?= 4.28444402

To the nearest hundredth

? = 4.28
