How do you find the area of a circle if only given the circumfe rence?
Area = Circumference squared divided by 4pi.
What is pi divided by 1 over 4?
It would be 4pi, or approximately 12.56637061435917.
Total surface area of a sphere with a radius of 4?
To find the surface area of a sphere, the formula is: 4pi*r2So plug in numbers: 4pi(4)24pi(16)=64pi
Which of the following is equivalent to the ratio of the circumference to the radius of a circle - A. pi divided by 2 B. pi C. 2pi D. 4pi?
The answer is C = 2*pi.
What is the surface aea of the sun?
The sun's surface area is 4pi r2 = 4pi (700 Mm)2 = 6.1575E18 m2
What size circle has numerically same perimeter and area?
A circle with radius=2. (pi*2^2=4pi and 2*2pi=4pi)
A sphere has a volume of 106 cm3 What is its radius?
The volume of a sphere is: V = 4/3 pi r3 so that 3V = 4 pi r3 r3 = 3V/4pi r3(1/3) = (3V/4pi)1/3 r = (3V/4pi)1/3 = [(3)(106 cm3)/4pi]1/3 r ≈ 2.94 cm
What is the circumference of the circle if the radius is 2?
4pi~ 12.566
What is the volume of a sphere with the diameter of 8 feet?
Volume of a sphere = 4pi*r^3 2r = d, so Volume of a sphere = 4pi*(4)^3 Volume = 256pi
How do you find the area of a circle with the circumference?
The area of a circle is (pi x radius squared) A = πr2 The circumference is (pi x diameter) C = π (2r) So if you have the circumference, the area is the circumference squared, divided by 4pi (about 12.566). A = C2/4π Example: A circle with a diameter of 6 inches has a radius of 3 inches Area A = pi (32) or about 28.27 square inches Circumference C = pi (6) or about 18.85 inches Using C2/4pi, the area is 18.85 x 18.85 / 12.566 = about 28.27 square inches
How do you find the area of a prism and a sphere?
Area of a sphere = (4pi/3) x (radius)3 Area of a prism depends on its shape, how many faces, etc.
What is the surface area of a ball with a circumference of 9 inches?
Part 1: Find the radius C = 2pi R Part 2: A=4pi(R*R)
