Convert the angle θ= 3π ​/5 radians to degrees. Express your answer exactly.<br><br>108
Olegator [25]

Answer:

216°

Step-by-step explanation:

Conversion from Radians to degrees : -

( θ * 360 ) / π

θ = 3π / 5

θ = ( 3π / 5 * 360 / π )

= ( 3 * 360 * π ) / ( 5 * π )

= ( 3 * 360 ) / 5

= 3 * 72

θ = 216°

iVinArrow [24]

Answer:

HE WAS LAST SEEN HEADING NORTH

Step-by-step explanation:

360: A

25×10×40 = 10000: I

(15×10.5×20)/450 = 7: W

(35×16×50)/800 = 35: S

3168/(22×9) = 16: N

cuberoot(64) = 4: R

6.5×15×8.5 = 828.75: G

4×2×3 = 24: E

3885/(18.5×15) = 14: H

3³ = 27: T

½ (7×9×12) = 378: L

30×20×11 = 6600: D

3600/(2×4÷5) = 90: O

Answer:

The surface area of the cone=238.64feet^2

Step-by-step explanation:

The given figure is in the shape of a cone:

Diameter=8 feet\\\\Radius=8/2=4 feet

slant height(l)=15 feet

Surface area of the cone

                    =\pi rl+\pi r^2

As, \pi =\frac{22}{7}=3.14

Surface area of the cone =(3.14*4*15)+(3.14 *4*4)

                      =(3.14*60)+(3.14*16)\\\\=188.4+50.24\\\\

                     =238.64feet^2

The surface area of the cone=238.64feet^2
