Answer:
I am not sure if this is right but the answer is
The area of a circle with circumference 18π is 254.5
Answer:y=-4/5x+4
Step-by-step explanation:
Given the expression
-2 + 6.45z - 6 + (-3.25z)
First, classify like terms, constant with constant, coefficient-variable with coefficient-variable
-2 + 6.45z - 6 + (-3.25z)
= 6.45z + (-3.25z) - 2 - 6
Second, combining like terms
= 6.45z + (-3.25z) - 2 - 6
= 6.45z - 3.25z - 8
= 3.20z - 8
The simplest form is 3.20 - 8
Step-by-step explanation:
V = 1/2 a x c x h
1/2 * 7*12*18 = 756 yd ^3
