Step-by-step explanation:
<h2>a).</h2>
To find the area of the circle we must first find the radius using the formula
radius = diameter / 2
From the question
diameter = 21 ft
The radius is
21/2 = 10.5 ft
Area of a circle = πr²
where r is the radius
Area = π(10.5)²
= 110.25π
<h3>= 346.36 cm²</h3>
<h2>b).</h2>
Circumference of a circle = πd
where d is the diameter
Circumference = π(21)
<h3>= 65.97cm</h3>
