If the diameter is 16 what is the circumference?
Sixteen times pi. 16*3.1416
If the radius of a circle is doubled what happens to the area?
It quadruples. The area of a circle is Pi (about 3.14159) times the radius squared. So if you double the radius (say from 2m to 4m), you area will change from 4*Pi to 16*Pi (4 times what it was originally).
A circle has a circumference of 16 pi inches what is its radius?
The formula where C=circumference, R=radius is C = 2 pi R Since C = 16 pi inches and 16 pi = 2 pi R we can solve for R and get R= 16 pi /2 pi = 8 Therefore the Radius is 8 inches.
Radius of a circle is 8 m what is the circumference?
Circumference of the circle: 2*pi*8 = 16*pi m
How do you find the perimeter and area of a circle?
perimeter (circumference): diameter times pi (3.14) area: radius times radius times pi (3.14) Area = pi*radius squared Circumference = 2*pi*radius or pi*diameter
Circumference is 16 times pi what is the diameter?
If the circumference of a circle is 16 linear units times pi, then its diameter 16 linear units.
What is pi times 16?
16 x 3.14 = 50.24
If the diameter is 16 what is the circumference?
Sixteen times pi. 16*3.1416
What is the circumference of a circle with a diameter of a 16 in?
16 times pi = approx 50.3 "
What is the surface area of a cylinder with a radius of 8 and a length of 20?
The surface area is equal to the (circumference of the base) times (the length). Circumference of the base = (2 pi) times (radius) = 16 pi Surface area = (16 pi) times 20 = 320 pi = 1,005.310 square units (rounded to 3 decimal places)
If the diameter is 16 what is the area?
It will be diameter times pi or 3.14 or 3
What is the area of a circle whose circumference is 8 times pi?
c=pi*8 diameter = 8 radius = 4 area = pi * 16
What is the circumference of a circle whose radius is 16 in terms of pi?
The circumference of a circle is its diameter times pi, which is the same as twice the radius times pi.A = 2r (pi)In this instance, the circumference is 32(pi) inches(about 100.53 inches)
What is the circumference of a circle with the diameter of 16in?
Circumference of a circle is the diameter times pi or 2pi times the radius. Given the diameter, circumference = 16 times pi. So, the circumference is 16pi or 50.265
What is the surface area of a cylinder that has a 6 feet radius by 16 feet length?
Area of a cylinder equals base (pi times the square of the radius) times height. For purposes of demonstration I will be using an approximation of pi, 3.1415926, though in practive the pi key on your calculator will yield more precise results. A= (16[height])(3.1415926[pi])(6[radius])^2 A= (16)(3.1415926)(36) A= (576)(3.1415926) A~ 1809.557338
What are the radius and circumference of a circle when 0.75 of its area covers 48 times pi square inches?
If 75% = 48*pi then 100% = 64*pi Radius = 8 inches Circumference = 16*pi inches
What is pi times pi divided by pi plus pi minus pi times pi?
the same as pi squared, which is 9.86960440109
