Question

9) The diameter of a circular ice skating rink is 32 feet. What is the approximate area of the ice skating rink? Use a = 3.14. a) 803.84 square feet b) 50.24 square feet c) 100.48 square feet d) 64 square feet​

Answer 1

a) 803.84 square feet

Explanation:

`\sf{area~of~circle~=~\pi r^(2) }\\\sf{radius~ =~half~of~diameter}`

so 32 / 2 = 16 = radius

`\sf{radius^(2) = 16^(2)=256}`

256 x 3.14 (because we are taking π as 3.14)

= 803.84

Hope this helps! If you need any further explanation, let me know!
