What is the area of a basketball hoop if the radius is 14 cm?
a = pi r sq. a = pi 14 sq. or pi 196 a= pi X 196 if you leave in terms of pi
How do you find the circumfrence of a circle with the radius?
two times the radius times pi
How do you find the pi circumference and area of circles?
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
How do you get from the radius to the circumference?
(radius+radius) times pi
What is the surface area of a cylinder with the height of 32ft and the radius of 15 ft?
This surface can be divided into three parts: the curved surface of the side, which can be unrolled to form a rectangle, and the flat circular bases at each end. The area of each base is pi times the square of the radius, or 225 pi square feet, so the two of them add up to 450 pi sq. ft. The rectangle is 32 ft. by the circumference of each base (2 pi times the radius, or 30 pi feet), so its area is 960 pi sq. ft. Altogether the surface area is thus 1410 pi sq. ft., which works out to 4,429.7 sq. ft., rounded to 5 significant digits.

How do you use pi to determine circumference?
Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)
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
How many sq inches in a 6 circle?
Area of a circle: pi*radius*radius
How do you find the circumfrence of a circle with the radius?
two times the radius times pi
If a circle is 15 ft across how many sq ft in it?
Roughly 177. Radius (7.5) squared times Pi.
What is the formula for volume and surface area of a cylinder?
* means times/multiplied by Volume of cylinder: pi*radius sq.*height Surface Area of Cylinder: (2*pi*radius sq.) + (2*pi*radius*height) Formula For Surface Area sa=(2x(3.14)r2+[2x(3.14)xr]xh Formula For Volume (3.14)r2xh
What is Pi times radius times radius?
The answer is Pi times radius squared. Although you can't know anymore since you don't give what the radius is. Although, Pi can be simply referred to as 3.14
How do you find the pi circumference and area of circles?
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
Is circumfrience pi times radius to the 2?
circumfrience is pi times radius to the 2 i think
Is circumference radius times pi?
NO!!!! C = 2 pi r C = pi d In words ; Circumference equals two times 'pi' times radius or , circumference equals 'pi' times diameter. NB The diameter is twice the radius. Also A = pi r^(2) In words, Area equals 'pi' times the radius squared. Read learn and comit to memory these two circle equations.
How do you get from the radius to the circumference?
(radius+radius) times pi
