Answer:
56.52 cm³
Step-by-step explanation:
Use the cone volume formula, V = [tex]\pi[/tex]r²[tex]\frac{h}{3}[/tex]
If the diameter of the cone is 6 cm, then the radius is 3 cm.
Plug in 3.14 as pi, 3 as the radius, and 6 as the height into the equation:
V = (3.14)(3²)[tex]\frac{6}{3}[/tex]
V = (3.14)(9)(2)
V = 56.52
So, the volume of the cone is 56.52 cm³

Answer:
Distance between points (2, 1) and (8,9) is 10.
Step-by-step explanation:
let me know if you need an explanation :)
hope this helps and is right. p.s i really need brainliest :)
Answer:
10
Step-by-step explanation:
distance formula is the square root of x sub 1 - x sub 2 quantity squared +y sub 1 + y sub 2 quantity squared. In this case it would look like the square root of (8-2)^2 +(9-1)^2. this would simplify to the square root of 100, which is 10.

Rocco has a weekly reading schedule, reading for 4.5 hours per day on some days and 3.5 hours per day on the other days. He reads a total of 25.5 hours in a seven-day week. On how many days does he read for 4.5 hours?
Answer:
x = days he reads for 4.5 hours = 1 day
y = days he reads for 3.5 hours = 6 days
Step-by-step explanation:
Let
x = days he reads for 4.5 hours
y = days he reads for 3.5 hours
x + y = 7 (1)
4.5x + 3.5y = 25.5 (2)
From (1)
x = 7 - y
Substitute x = 7 - y into (2)
4.5x + 3.5y = 25.5 (2)
4.5(7 - y) + 3.5y = 25.5
31.5 - 4.5y + 3.5y = 25.5
- 4.5y + 3.5y = 25.5 - 31.5
-y = -6
y = 6
Substitute y = 6 into (1)
x + y = 7 (1)
x + 6 = 7
x = 7 - 6
x = 1
x = days he reads for 4.5 hours = 1 day
y = days he reads for 3.5 hours = 6 days

A number is between 40 and 45. It has prime factors of 2 and 7. What is the number?
Answer:
42
Step-by-step explanation:
42 is divisible by both 7 and 2
The number which has prime factors of 2 and 7 and in between 40 and 45 is 42.
Given that, a number is between 40 and 45. It has prime factors of 2 and 7.
What are prime factors?The process of writing a number as the product of prime numbers is prime factorization. Prime numbers are the numbers that have only two factors, 1 and the number itself.
The numbers between 40 and 45 are 41, 42, 43 and 44.
The factors of the numbers are as follows
41 = 1×41
42 = 1×2×3×7
43 = 1×43
44 = 1×2×2×11
Therefore, the number which has prime factors of 2 and 7 and in between 40 and 45 is 42.

can i please have help i dont know the answer to this one
Answer:
B
Step-by-step explanation:
make y the subject please help
Step-by-step explanation:
Square both sides and you will get
3xy/(x + y) = 4
Multiplying both by (x + y), we get
3xy = 4(x + y) = 4x + 4y
Put all the terms containing y to the left side:
3xy - 4y = 4x
y(3x - 4) = 4x
or y = 4x/(3x - 4)

10n+0.3=0.1n+0.3 Solve for N
Answer:
n=0
Step-by-step explanation:
Let's solve your equation step-by-step.
10n+0.3=0.1n+0.3
Step 1: Subtract 0.1n from both sides.
10n+0.3−0.1n=0.1n+0.3−0.1n
9.9n+0.3=0.3
Step 2: Subtract 0.3 from both sides.
9.9n+0.3−0.3=0.3−0.3
9.9n=0
Step 3: Divide both sides by 9.9.
9.9n/ 9.9 = 0/ 9.9
n=0
Answer:
n=0
Answer:
0
Step-by-step explanation:
10n - .1n = 9.9n
9.9n + .3 = .3
subtract .3 from the other one and get 0
9.9n = 0 then divide and it comes out to 0

Answer:
267.95cm^3
Step-by-step explanation:
S= 4πr^2
Surface area is 200.96
π= 3.142
200.96= 4×3.142×r^2
200.96= 12.57r^2
r^2= 200.96/12.57

= √15.99
r = 3.9
Volume= 4/3πr^3
= 4/3× 3.142×3.9^3
