What else can I help you with?
How do you get the radius when you are given the circumference?
Let C be the circumference, r be the radius, and (pie)= 3.141592654 C = 2 x (pie)x r r = C ÷ (2 x (pie))
How do you find area of a cylinder?
(2)(pie)(r)(h) + (2)(pie)(r - squared) = tot area of a cylinder
Is the circumference 3 times the radius?
No, the formula for a circumference of a circle is 2(pie)r For example, if r is 6, the the circumference is 12(pie)
What is the radius of an 18ft circumference pool?
since c of the pool is 18 then 2pieR = 18 /2 pieR=9 /pie R=9/pie the radius is 9/pie
what- a pie tin has a circumference of about 25 inches.Which is the best approximation for the radius of the tin?
The pie tin is circular. So apply the circular equation/ C = 2 pi r Algebraically rearrange r = C / ( 2 pi) r = 25/(2 x 3.14) C = 25/ 6.28 C = 3.9808.... incges ~ 4 inches,.
What are the steps for area of a circle?
pi multipied by the radius sqaured all divided by 2 pi*r^2 ------ 2
How do find the diameter of the circle in terms of pi?
perimeter of a circle = pie *r^2 Hence r^2 = perimeter/ pie hence r = (perimeter/Pie)^1/2 Hence diameter = 2r= 2* ( perimeter?pie) ^1/2
What is the surface area of half a sphere?
its 2 pie r squared BUT you have to add back the base (a circle) which is pie r2 The original formula is 4 pie r squared Your new formula is (2 pie r squared + pie r squared)
How do you get the radius when you are given the circumference?
Let C be the circumference, r be the radius, and (pie)= 3.141592654 C = 2 x (pie)x r r = C ÷ (2 x (pie))
What is 2 sqaured?
2 x 2 = 4
How do you find area of a cylinder?
(2)(pie)(r)(h) + (2)(pie)(r - squared) = tot area of a cylinder
What is the radius of a circle with circumference of 2 pie?
radius = 1, C=2(pie)r
What is and pie r 2 an example of?
A circumference.
What is the circumference and area of a 8 in circle?
if the radius is 8 in then circumference = 2 pie r= 2 * 3.14 * 8= 50.24 in area = pie * r * r = 3.14 *8 * 8= 200.96
