Step-by-step explanation:

you know the formulas ?

the area of a circle is : pi×r²

the circumference of a circle is : 2×pi×r

with r being the radius, which is half of the diameter.

so, here, r = 10/2 = 5 m

area = pi×r² = pi×5² = pi×25 or 25×pi m²

circumference = 2×pi×r = 2×pi×5 = 10×pi m

for the approximation we make the calculations with pi on the calculator and round to the nearest hundredth.

area = 25×pi ≈ 78.54 m²

circumference = 10×pi ≈ 31.42 m
