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.
