Question

A round table top has a diameter of 2.6 meters.What is its surface area

Answer 1

Hello!

To find the area of a circle you use the equation

$\pi r^{2}$

r is radius which is half the diameter

r = 2.6 / 2

r = 1.3

Put in the values you know

$\pi 1.3^{2}$

Square the number

$1.69 \pi = 5.31$

The answer is $1.69 \pi$ or ≈5.31

Hope this helps!

Answer 2

That's just area of a circle

remmber that $A=\pi r^2$ where r=radius and A is area and pi is pi or about 3.14159265

so if diameter is 2.6, ah, tricky, they give you dameter
rmemeber that d/2=r so 2.6/2=d/2=r=1.3

so
$A=\pi r^2$
$A=\pi (1.3)^2$
using your calculator
$A=5.309 m^2$


the surface area is $5.309 m^2$
