The volume of a square prism with height of 21 inches and each side of the base s inches is given by the expression 7s2. Find th
Murljashka [212]

Answer:

63 cubic inches.

Step-by-step explanation:

The volume of a prism is given by, A =  \frac{1}{3} \times (\textrm {Base Area}) \times (\textrm {Height})

The base area for a square prism with sides s inches is s² sq. inches.

So, the volume of a square prism with a height of 21 inches and each side of the base s inches is given by the expression, V = 7s² cubic inches.

Therefore, if s = 3 inches, then volume will be, V = 7(3²) = 63 cubic inches. (Answer)

In ΔKLM, l = 570 cm, k = 490 cm and ∠K=46°. Find all possible values of ∠L, to the nearest degree.
Katen [24]

Step-by-step explanation:

In ΔKLM, l = 570 cm, k = 490 cm and ∠K=46°. Find all possible values of ∠L, to the nearest degree.

K

L

M

k = 490

l = 570

46°

?°

\frac{\sin A}{a}=\frac{\sin B}{b}

a

sinA

​  

=  

b

sinB

​  

 

From the reference sheet (reciprocal version).

\frac{\sin L}{570}=\frac{\sin 46}{490}

570

sinL

​  

=  

490

sin46

Plug in values.

\sin L=\frac{570\sin 46}{490}\approx 0.836783

sinL=  

490

​  

≈0.836783

Evaluate.

L=\sin^{-1}(0.836783)\approx 56.8\approx 57^{\circ}

L=sin  

−1

(0.836783)≈56.8≈57  

∘

 

Inverse sine and round.

\text{Quadrant II: } 180-57=123^{\circ}

Quadrant II: 180−57=123  

∘

 

Sine is positive in quadrants 1 and 2.

\text{Check for possibility:}

Check for possibility:

No triangle's angles may add to more than 180.

46+57=103

46+57=103  

∘

←Possible

Less than 180.

46+123=169}

46+123=169

←Possible

Less than 180.
