Diameter = 4 cm
Radius = Diameter/2 = 2 cm
Area of circle :




Circumference of circle :



<h2>Therefore, </h2><h3>Diameter = 4 cm</h3><h3>Radius = 2 cm</h3><h3>Area = 12.56 cm²</h3><h3>Circumference = 12.56 cm</h3>
<h2><u>

</u></h2>
Circumference = 15 feet (given)
Radius :







Diameter = r×2 = 2.38 × 2 = 4.76 feet
Area :



<h2>Therefore, </h2><h3>Diameter = 4.76 feet</h3><h3>Radius = 2.38 feet</h3><h3>Area = 17.78 ft²</h3><h3>Circumference = 15 feet</h3>
<h2><u>

</u></h2>
Diameter = 2 cm (given)
Radius = D/2 = 2/2 = 1 cm
Circumference :



Area :



<h2>Therefore, </h2><h3>Diameter = 2 cm</h3><h3>Radius = 1 cm </h3><h3>Area = 3.14 ft²</h3><h3>Circumference = 6.28 feet</h3><h2 /><h2><u>

</u></h2>
Radius = 4.3 mm
Diameter = r×2 = 4.3 × 2 = 8.6 mm
Circumference :



Area :




<h2>Therefore, </h2><h3>Diameter = 8.6 mm</h3><h3>Radius = 4.3 mm</h3><h3>Area = 58.95 mm²</h3><h3>Circumference = 27 mm</h3>
Answer:
Step-by-step explanation:
V= 2pi^h
120=2(3,14) h
120/6,28= 19 feet
Answer:
220 Yards per minute
Step-by-step explanation:
15miles/2hours
**To show mph**
7.5miles/1hour ; Now you want to convert the miles into yards and the hours into minutes.
7.5*1,760/60minutes
13200/60 minutes ; now divide to show yards per minute.
220ypm
