Hi there!
Using the equation for the area of a circle, we can simply substitute pi with its numerical value of 3.14 and r with the radius given.
1.) Area = (3.14)(6cm)² = 113.0 cm²
2.) Area = (3.14)(28in)² = 2461.8 in²
3.) To find radius, first we must divide the diameter in half. So, 11/2 = 5.5 ft
Area = (3.14)(5.5ft)² = 95 ft²
4.) Similar to 3, to find radius, first we must divide the diameter in half. So, 10.5/2 = 5.25 in
Area = (3.14)(5.25in)² = 86.5 in²
5.) Area = (3.14)(6.3mm)² = 124.6 mm²
6.) Area = (3.14)(3
yd)² = 33.2 yd²
