Container at the petting zoo holds 8138.88 cm³ of green visitors can feel peoples homes with rain from the container the cones h

slamgirl [31]

Answer:

We can fill the cone 54 times with the grain.

Step-by-step explanation:

Amount of grain = 8138.88 cm³

Dimensions of cone:

Radius = 4 cm

Height = 9 cm

Volume of 1 cone =

$V = \displaystyle\frac{1}{3}\pi r^2 h\\\\V = \frac{1}{3}(3.14)(4)^2(9)\\\\V = 150.72\text{ cubic cm}$

Let n be the number of times the cone that can be filled.

Thus, we can write:

$\text{Amount of grain} = n \times \text{Volume of cone}\\8138.88 = n \times 150.72\\\\n = \dfrac{8138.88}{150.72}\\\\n = 54$

Thus, we can fill the cone 54 times with the grain.

Answer:

7Sin^2x+(7-6)sinx-6=0

7sin^2x+7sinx-6sinx-6=0

7sin(sinx+1)-6(sinx+1)=0

(sinx+1)(7sin-6)=0

either, or,

sinx+1=0 7sin-6=0

sinx=-1 sin=6/7
