Hello!
To find the volume of a rectangular prism you use the equation
V = lhw
v is volume
l is length
h is height
w is width
Put in the values you know
180 = 6 * 5 * w
Divide both sides by 6
30 = 5 * w
Divide both sides by 5
6 = w
Answer is 6cm
Hope this helps!
Answer:
C = 6.28
A = 3.14
Step-by-step explanation:
use the equations for area and circumference to solve
C = pi d
A = pi r^2
I like to remember these using the saying Cherry pie's delicious, Apple pie's are too so Cherry = pi's delicious, Apple = pi's r 2
so with the diameter of 2 plug in to get circumference
C = 3.14 (2)
C = 6.28
and the equation for area uses radius not diameter but we know that d/2=r so radius is 1, plug in to solve
A = 3.14 (1)^2
A = 3.14 (1)
A = 3.14
Hope this helps! :)
Answer:
Step-by-step explanation:
If he earns $48 dollars in 3 hours, you need to divide 48 by 3 to work out how much he makes per hour. and 48/3 = 16. So he makes $16 dollars an hour.
FIRST Remove parentheses.
−12+8+5-9
Simplify -12+8 to -4
-4 + 5 — 9
Simplify
−4 + 5 −4+5 to 1
1 — 9
Simplify
-8 is your answer
