Answer:
15.9 mm²
Step-by-step explanation:
We solve using Area of the circle formula
Area of a circle = πr²
Diameter of his friend's wand = 4.5mm
Radius = 4.5mm/2
= 2.25 mm
How much wire did his friend need to make the circular part of his wand? Use 3.14 for π
= 3.14 × (2.25mm)²
= 15.89625 mm²
Approximately = 15.9 mm²
Answer:
<h2>x=3</h2>
Step-by-step explanation:
Let's solve your equation step-by-step.
8.88=−2.22(x−7)
Step 1: Simplify both sides of the equation.
8.88=−2.22(x−7)
8.88=(−2.22)(x)+(−2.22)(−7) (Distribute)
8.88=−2.22x+15.54
Step 2: Flip the equation.
−2.22x+15.54=8.88
Step 3: Subtract 15.54 from both sides.
−2.22x+15.54−15.54=8.88−15.54
−2.22x=−6.66
Step 4: Divide both sides by -2.22.
−2.22x
/−2.22
=
−6.66
/−2.22
x=3
Answer: ×/2 + 9 =
Step-by-step explanation: when a sentence needs to be visualized it is best to strat from the outside.
So if nine more than blah blah equals 21,
... +9 = 21
Answer:
48 because the additive inverse is what you add to make zero
Answer:
Step-by-step explanation:
y is the value obtained from 4 and 12
y^2 = 4 * 12 Combine
y^2 = 48 Square root both sides.
√y^2 = √48
y = √(3 * 4 * 4)
y = 4√3
Use the Pythagorean Theorem to obtain x
x^2 = y^2 + 4^2
x^2 = 48 + 16
x^2 = 64 Take the square root of both sides
√x^2 = √64
x = 8
