Austin keeps a right conical basin for the birds in his garden as represented in the diagram. The basin is 40 centimeters deep,
Lina20 [59]

The shortest distance between the tip of the cone and its rim exits 51.11cm.

<h3>What is the shortest distance between the tip of the cone and its rim?​</h3>

If you draw a line along the middle of the cone, you'd finish up with two right triangles and the line even bisects the angle between the sloping sides. The shortest distance between the tip of the cone and its rim exists in the hypotenuse of a right triangle with one angle calculating 38.5°. So, utilizing trigonometry and allowing x as the measurement of the shortest distance between the tip of the cone and its rim.

Cos 38.5 = 40 / x

Solving the value of x, we get

Multiply both sides by x

$\cos \left(38.5^{\circ}\right) x=\frac{40}{x} x

$\cos \left(38.5^{\circ}\right) x=40

Divide both sides by $\cos \left(38.5^{\circ}\right)$

$\frac{\cos \left(38.5^{\circ}\right) x}{\cos \left(38.5^{\circ}\right)}=\frac{40}{\cos \left(38.5^{\circ}\right)}

simplifying the above equation, we get

$x=\frac{40}{\cos \left(38.5^{\circ}\right)}

x = 51.11cm

The shortest distance between the tip of the cone and its rim exits 51.11cm.

The value of 3 in 3,456 is what times the value of 3 in 546,300
S_A_V [24]
The value of 3 in 3,456 is 3000 and the value of the 3 in 546,300 is 300 so you would multiply 3000*300 if I am correct.
I hope this could help.

Sladkaya [172]

Answer:

A

Step-by-step explanation:

A]

7*5 = 35+15 = 50

10*70 = 70 +14 = 85

15*7 = 105 +15 = 120

20*7 = 140+15 = 155

B]8.50*5 = 42.5

C]10*5 = 50

10*10 = 100

D] = 8*5 = 40 +10 = 50

10*8 = 80+10 = 90
