1. I would agree with 5 because a cone is 1/3 of its cylinder and 1/3 of 15 is 5

2. If the diameter is 6, then the radius is 6 ÷ 2 = 3, which also means the height is 3 × 3 = 9. To find the volume, we first need the area of its base circle, and we get this by doing π × radius^2 = π × 3^2 = 9π. Because they want us to use 3.14 as π, you do 9 × 3.14 = 28.26. We figured out the height earlier, so now all you do is 28.26 × 9 = 254.34

I hope this helps!

lana [24]

Answer:

11 units

Step-by-step explanation:

Length of side PS can be calculated using the distance formula, d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Where,

P(-2, 5) = (x_1, y_1) (the coordinate of P is gotten from the graph)

S(9, 5) = (x_2, y_2) (given)

PS = \sqrt{(9 - (-2))^2 + (5 - 5)^2}

PS = \sqrt{(11)^2 + (0)^2}

PS = \sqrt{121} = 11 units

In a bag of marbles, 6 are blue. The probability of picking out a blue marble from the bag is 3/5. How many marbles are in the b
postnew [5]

Answer: 3/5 = (6/10). There are 10 TOTAL marbles in the bag.

Step-by-step explanation:

Since it is a question of fractions, you can assume any reasonable number and work with the numbers. We know initially that there are 6 marbles and they are ALL blue and the rest are another color or colors. So BLUE = 6/10 and the other colors 4/10 for 2/5.

Can someone please solve this for me
Savatey [412]

Answer:

m<JKD = 22 degrees

Step-by-step explanation:

21x + 5 + 4x + 2 = 132

25x + 7 = 132

25x = 125

x = 5

m<JKD = 4x + 2

4(5) + 2

20 + 2

22
