Question

The diameter of the given circle is 37 cm. The value of 'a' is the smallest possible integer value for which 'b' will also be an integer. What is the perimeter (in cm) of the rectangle? a b a. 85 b. 78 c. 94​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Option ( b ) is correct.

Complete step-by-step solution:

2πr−r=37

r(2π−1)=37

r(2⋅227−1)=37

r(447−1)=37

r(44−77)=37

r(377)=37

r×37=37×7

r=7

So, the radius is equal to 7 cm, the diameter of circle =2×r  

2×7=14 cm

Hence, the diameter of the circle equals 14 cm.
