Answer:

The volume is about 4.24 cm^3.

Step-by-step explanation:

From the question we are told that:

Diameterd= 3-cm

Radius r=d/2=>1.5cm

Height risen14.6-14=0.6cm

Generally the equation for Volume of a Key is mathematically given by

Since Volume of a cylinder is Given as

V=\pir^2h

Therefore

V=\pi*1.5^2*0.6

V=4.2417\\\\V=4.24 cm^3

Correct Option A

The volume is about 4.24 cm^3.

Solve: log (7t + 2) = 2<br>t =​
IrinaK [193]

Answer:

t = 14

Step-by-step explanation:

log (7t + 2) = 2

Raise each side to the power of 10

10 ^log (7t + 2) =10^ 2

7t+2 = 100

Subtract 2 from each side

7t+2-2 = 100-2

7t = 98

Divide each side by 7

7t/7 = 98/7

t = 14

Identify the property used in the first five steps to solve the equation 2(x-5)-6x=-22
Alona [7]
To answer this question, you need to multiply the number inside the bracket first. Then you can move the number to the right side of the equal sign and keep the x on the left side of the equal sign. The step would be like this
2(x – 5) - 6x= -22(2x - 10) - 6x = -222x - 6x  = -22 +10-4x= -12x= -12/-4x=3
Hope this helps!!!

This is the associative property of addition (D).
It states that when adding three terms, the sum is equal no matter the grouping (parentheses).
