Answer:

2411.52 cm³

Step-by-step explanation:

V = (2/3)πr³ Use the equation for volume of a hemisphere

V = (2/3)(3.14)(8)³ Simplify the exponent

V = (2/3)(3.14)(512) Multiply

V = 1071.79 cm³

V = πr² h/3 Now find the volume of the cone

V = (3.14)(8)²(20/3) Simplify the exponent

V = (3.14)(64)(20/3) Multiply

V = 1339.73 cm³

Add both of the volumes together to get the volume of the figure.

1071.79 + 1339.73 = 2411.52 cm³

Eric and Mark were at a ball game and visited the concession stand. They each got a hamburger, and Mark got lemonade and some co

EastWind [94]

So here is the answer. Given that both Eric and Mark got a hamburger which is $4 each. Mark got a lemonade and some cotton candy which costs $5.
So this gives them a total of $4, $4, $5, $?(lemonade). Partial sum is $13 without the lemonade. Since Eric got a $2, the total bill was deducted with $2 and the rest of the amount is $14.50. Therefore, the total bill would have been $16.50. So $16.50 minus $13 (partial sum) is $3.50. So the lemonade costs $3.50. Hope this helps.

Find the value. Please

The cosine ratio is adjacent leg divided by the hypotenuse.
The hypotenuse in a right triangle is the longest side and it is opposite the right angle.
An adjacent leg is the side that has an endpoint that is at the vertex of the angle and the other endpoint is at the vertex of the right angle.

cos A = $\frac{12}{20} = \frac{3*4}{5*4} = \frac{3}{5}$
ANSWER: $cosA= \frac{3}{5}$
