Question

Gale builds a circular pen in his yard for his dog. The pen has a radius of 10 ft. There is a law in Gale's town which states that all dogs must have at least 300 ft2 of room in their pen. Does Gales' pen meet the standards?

A) No. A = 62.8 ft2
B) No. A = 98.596 ft2
C) Yes. A = 314 ft2
D) Yes. A = 985.96 ft2

Answer 1

The correct answer is C) Yes.A = 314 ft2

Explanation:

Yes. A = 314 ft2 is the correct answer. The area of a circle can be found using the formula A = πr2, where π ≈ 3.14 and r = 10.

A = (3.14)(102) = (3.14)(100) = 314 ft2.

Since 314 is greater than 300, his pen meets the standards.

Answer 2

area of circle=pi times r^2
r=10
subsitut eans solve
area=pi times 10^2
area=pi times 100
if we aprox pi to 3.14 then
area=3.14 times 100
area=314
we can see that this is answer C
