Equation (4) in (3)
Put equation (6) into equation (5)
z=3
Put z=3 into equation (6)
y=2(3)-4=2
Put y=2 and z=3 into equation 4
The solution is x=1,y=2,z=3
Volume = πr²h
Given that the volume = 250π cm³ and radius = 5cm, find the height:
250π = π(5)²h
250π = 25πh
h = 250 ÷ 25π
h = 10 cm
Answer: The height is 10 cm
Answer:
Step-by-step explanation:
1.x^5 times x^3
<u>To multiply powers of the same base, add their exponents.</u> Add 5 and 3 to get 8.
