WebSurface area of a sphere. The surface area formula for a sphere is 4 x π x (diameter / 2) 2, where (diameter / 2) is the radius of the sphere (d = 2 x r), so another way to write it is 4 x π x radius 2.Visual on the figure below: A sphere's surface area can be calculated just by knowing its diameter, or radius (diameter = 2 x radius). π is, of course, the well-known … WebApr 10, 2024 · Diameter Formula Using Area of Circle. The diameter of a circle formula can be derived using the formula of area of the circle i.e, $\mathtt{Area} (A) = \pi \times \mathtt{Radius}^{2} ... Radius 16 cm, Diameter 38 cm. 2. Find the radius and diameter of the following circle. A) Radius 23 m, Diameter 98 m. B) Radius 12 m, Diameter 24 m.

WebOct 13, 2024 · However, we have to find the area. The formula for the area of a circle is: A= We know that r=4, so all we have to do is plug it into the formula: A= Remember that only the radius is squared. A= A=50.265. Let's round to the nearest tenth: A=50.3. Hope this helps you! Let me know if you have any questions! WebTo find the radius from the diameter, you only have to divide by two: r=d/2 r = d/2. If you know the circumference it is a bit harder, but not too bad: r=c/2\pi r = c/2π. Dimensions of a circle: O - origin, R - radius, D - diameter, C - circumference ( Wikimedia) Area, on the other hand, is all the space contained inside the circle. dark desert highway svg free

WebThis tool will calculate the diameter of a circle from the area, and will convert different measurement units for area and diameter. Formula. The formula used to calculate the circle diameter is: ø = 2 x √(A / π) Symbols. ø = Circle diameter; A = Circle area; π = Pi = 3.14159… Area of Circle. Enter the area contained within a circle ... WebMay 11, 2024 · Answer: Your answer is 64pi square inches. Step-by-step explanation: The diameter is 16 so the radius is 8. So the area is pi(r^2)= pi(8^2) =64pi square inches WebFeb 21, 2024 · nobrains. Formula for area of a circle is pi*radius^2. The radius of a circle is half the diameter. Since the diameter given is 16 inches, the radius is 8 inches. Using the formula, we find that the area is pi* (8 inches)^2 = 64pi inches^2. Advertisement. dark deity weapon triangle
