1 answer:

7 0

2^3 = 8
11/9 = 1.22
sqrt 5 = 2.24
sqrt 20 = 4.47
sqrt 11 = 3.32

least to greatest : 11/9, sqrt 5 , sqrt 11 , sqrt 20, 2^3

Find the volume of a right circular cone that has a height of 10.7 in and a base with a diameter of 8.1 in. Round your answer to

scoundrel [369]

Answer:

$V = \pi r^2 h$

And for this case the value for the height is $h = 10.7 in$ the diameter is provided $D = 2r = 8.1 in$ so then the radius is given by:

$r = \frac{D}{2}=\frac{8.1 in}{2}= 4.05 in$

Then we can find the volume with the first formula and replacing we got:

$V = \pi (4.05in)^2 (10.7 in)= 551.4 in ^3$

The final answer for this case would be 551.4 cubic inches

Randi scored r points at a basketball game.

steposvetlana [31]

Answer:

b,f

Step-by-step explanation:

b: if sandi scored 3 more points than randi, then sandis points are equal to 3+randi

f: so the equation is 3+r=s,

so input values

3+r=18

r=18-3

r=15

Use words to explain why the two equations below are equivalent

DiKsa [7]

Answer:

These equations are equivalent because after you solve the equation the answer are the same. For example 2+2 and 3+1 are equivalent. They both equal four. In these problems are x=3 and x=3.5 they are the same beause of the answer on problem 2 6-x. That makes them both have the same answer

Step-by-step explanation:

7x-9=12

+9=+9

7x=21

/7=/7

x=3
