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:
B. 60cm
Step-by-step explanation:
The area of parallelogram is calculated by multiplying b × h (b: base, h: height)
the base given here is 5 cm and height is 12 cm
5×12 = 60
Answer: Yes you can.
Step-by-step explanation:
Any common formative can boost up a grade my 0. anything. If you do extra credit, your grade will boost up to an 80 overall.
I will tell you how to solve the first one, and then you have to try to do the rest of them by yourself. :) because doing math is also a process of learning.
31. \sqrt{6}(\sqrt{2}+\sqrt{6})
=\sqrt{12}+6 distribute and simplify
=2\sqrt{3}+6 take a 2 out, and you get the answer.
