The measure of the central angle of a sector of a circle is 90^{o}. The arc length of the sector is 3(pi) cm. What is the radius of the circle? 1. What is the radius if the area of a circle is: a. 4x^2(pi) ...
<p>To find the radius of the circle whose area is equal to the sum of the areas of two circles with radii 15 cm and 8 cm, we can follow these steps:</p><p><strong>Step 1: Calculate the area of the first circle</strong> The formula for the area of a circl
In summary, the formula to find the area of a sector in a circle is A = (πr^2θ)/360, where θ is the central angle in degrees. If θ is in radians, the formula becomes A = (r^2θ)/2. The sector area is simply a fraction of the total area of the circle. ...
The fixed point inside the periphery is known as the center while the constant distance of this point from the circumference is termed the radius of the circle. Let us suppose r be the radius of a circular geometry then its area is given by the below formula: ...
