Question

To the nearest tenth, find the area of
a circle with d= 8 km. Use 3.14 for pi

Answer 1

25.1

Explanation:

the formula for the area of a circle is A=3.14(pi)r² or A=3.14(pi)d

r = radius d = diameter

so

a = 3.14d

a= (3.14)(8)

a= (25.12) rounded to the nearest tenth = 25.1

hope this helps
