Answer:
78.5
Explanation:
Given:
Radius = 5
And for pi, we use 3.14.
Now let's find the formula for area of a circle:
A = πr^2
Where π represents pi (3.14) and r represents the radius.
Plug in the only value we know and need into the formula(the radius, which is 5.
A = πr^2
Substitute:
A = π(5)^2
Solve exponents first:
A = π25
A = 3.14(25)
A = 78.5 is the area.
