Can someone help me with my last question.
jek_recluse [69]

Given:

Volume of the cone = 23,942.5 cubic cm

Radius of the cone = 25 cm

The value of π ≈ 3.14

To find:

The height of the cone

Solution:

Volume of the cone formula:

$V=\frac{1}{3} \pi r^2h

Substitute the given values.

$\frac{1}{3} \times 3.14 \times 25^2\times h=23942.5

$\frac{1}{3} \times 3.14 \times 625\times h=23942.5

$654.17\times h=23942.5

Divide by 654.17 on both sides.

$\frac{654.17\times h}{654.17} =\frac{23942.5}{654.17}

h=36.6 cm

The height of the cone is 36.6 cm.

NEED HELP, PLEASE SHOW WORK. :(((
sukhopar [10]

Answer:

About 34 workers

Step-by-step explanation:

200/30 to find on average how many trees can be carved by one worker

The answer is 6.666, so just 6

Then 6*4=24 to figure out how many more trees can be carved by (4 more) workers

So, add 4 to 30 and about 224 trees can be carved.

A number is 3 1/3 greater than another. If the sum of the numbers are doubled the answer would be 19 1/2
Delicious77 [7]

Answer:

smaller number = 3 5/24

larger number =  6 13/24

Step-by-step explanation:

let the larger number = x

smaller number = y

x - y = 3 1/3 equation 1

2(x +y) = 191/2 equation 2

divide equation 2 through by 2

x + y = 9 3/4  equation 3

subtract equation 1 from 3

2y = 6 5/12

y = 77/12 x 1/2 = 3 5/24

substitute for y in equation 1

x - 3 5/24 = 31/3

x = 3 1/3 + 3 5/24

x = 6 13/24
