Step-by-step explanation:
Answer:
210 cm^2
Step-by-step explanation:
Let, a=37 cm, b=35 cm, c= 12 cm
s=(a+b+c)/2 = 42 cm
Δ=
Δ= 
Δ=210 cm^2

<h3>Given:</h3>
Circumference of the circle = 88 cm
π = 22/7
<h3>To Find:</h3>
The Diameter of the circle.
<h3>Formula:</h3>
Circumference of circle = 2πr
r = radius
<h3>Solution:</h3>
Circumference of the circle = 2πr = 88 cm
Circumference of the circle = πr = 88/2 = 44 cm
Circumference of the circle = r = 44 × 7/22 = 14 cm
r (radius) = 14 cm
d (diameter) = 2r = 2(14) = 28 cm
<h2>Answer:</h2>
Diameter of the circle = 28 cm
