Answer:
The circumference of the circle is 28.26 m.
The area of the circle is 63.585
.
Step-by-step explanation:
To solve for the circumference of the circle, start by using the circumference formula of a circle, which is
. However, 3.14 will be used instead of
for this formula.
First, the radius of the circle needs to be found. To find the radius of the circle, divide the diameter by 2 because the radius equals half of the diameter. The radius is 9 m divided by 2, which equals 4.5 m.
Next, plug in the radius into the formula, and the formula will look like
. Then, solve the equation, and the answer will be 28.26 m.
To solve for the area of the circle, start by using the area formula of a circle, which is
. However, 3.14 will be used instead of
for this formula.
For the area, plug the radius into the formula, and the formula will look like
. Then, solve the equation, and the answer will be 63.585

Answer:
If I could travel to any year in a time machine, I would choose a year in future. For example, 3050. Everyone assumes the future according to their own imagination. But nobody knows what it actually looks like. So, if I could time travel, I would travel to a year in future.
Answer: 10
Step-by-step explanation:
1. Write the fractions as 2/9 times 45/1.
2. Cross cancel 45 and 9 by dividing by 5, which now gives you 2/1 and 5/1.
3. Multiply 2/1 and 5/1 and you get 10.
I hope this helps!
Answer:
b .
x = 3
y = 3![\sqrt3](https://tex.z-dn.net/?f=%5Csqrt3)
Step-by-step explanation:
Using the pythagorean identities for 30-60-90° triangle,
we know the ratio of the sides is x - x√3 - 2x
Since 2x = 6
Then smallest side is x (opposite ∠30°) = 6/2 = 3
The other side y , opposite ∠60° will be x√3 or 3√3.
