Answer:

Step-by-step explanation:

The formula for the circumference of a circle is 2 $\pi$ r. So if we know that C=60 $\pi$ then we can trace our steps back. We are given that pi remains constant so we are left with the 2r from the formula and a 60. 60/2 =30.

The radius is 30cm

When is a zero not significant?

fomenos

Answer: A. When it comes after the decimal point, as in 4.000

Step-by-step explanation: If there are no other numbers after the zeros, there is no reason for them to be place holders. Zeros in decimals act as place holders such as in 4.09 or 4.0009. This actually does change the value of the decimal but 4.000 is just the same as a regular old 4. Hope this helps!

The diameter of a circle is 10 cm what is the angle measure of an arc Pi centimeters long

vredina [299]

We know that

[length of a circumference]=2*pi*r
diameter=10 cm
r=10/2-----> 5 cm
[length of a circumference]=2*pi*5-----> 10*pi cm

if 360° (full circle) has a length of -----------> 10*pi cm
X°---------------------------> pi cm
X=pi*360/10*pi------> 36°

the answer is 36°

What is the answer for this algebra question 4(2n-5)=3n+10

miss Akunina [59]

$4(2n-5)=3n+10\\\\
8n-20=3n+10\ \ \ |Subtract\ 3n\\\\
5n-20=10\ \ \ Add\ 20\\\\
5n=30\ \ \ |Divide\ by\ 5\\\\
n=\frac{30}{5}=6\\\\Solution\ is\ n=6.$
