no dum bicth im having trouble myself
It means to multiply the radius by itself: radius x radius
The diameter is twice the radius. So multiply the radius by 2
When you try to figure out an area of a circle, you square the radius, then multiply it by pi to get the area of a circle. A radius square is radius x radius, or radius squared.
What you would do is just multiply the radius by 2 because radius is 1/2 of the diameter.Example:A circle has a radius of 8 cm. What is the diameter?Just multiply 8 times 2 = 16The diameter of the circle is 16 cm.
The radius is 1/2 of the diameter, so if the radius is 20 units then the diameter is 40 units. You multiply the radius by 2 to get the diameter.
Multiply the radius by itself, then multiply the result by Pi.
you simply multiply the radius by 2 and multiply that by 3.14159
Multiply the radius by 2 and multiply the result by 3.141592654....(pi)
It means to multiply the radius by itself: radius x radius
Multiply the radius by 2.
Multiply the radius by the integer 3.
Multiply the radius 2x to get you answer. Example: Say your radius is 4. You multiply that by 2 (4 x 2 = 8)
double the radius or multiply by 2 the radius
You multiply the radius by 2. Then you multiply the product by pi (3.14)
No you don't multiply the 4 numbers you take radius times radius
Multiply the radius by 2.
Multiply the radius by 2, then multiply that result by the value of Pi - and you'll have your answer.
