Question

If the area of a circle is equal to sum of area of two circles of diameter 10cm and 24cm then find the diameter of longer circle

Answer 1

$286 \div 7$

Answer 2

Answer:

Step-by-step explanation:

radius of first circle is R=5cm  and second is r=12cm

πR^2 + πr^2 = πr^2

π5*5 + π12*12 = πr^2

25π + 144π = πr^2

169=r^2   ----------π pi is got canceled out

r=√169 = 13

diameter of longer circle is 2r = 2 x 13 = 26cm
