Is 800 cm bigger than 8 m
Soloha48 [4]
Convert 8m to cm.

1 m = 100 cm

Multiply:

8 * 100 = 800

So 8 m is equal to 800 cm.

Both of them are equal, so 800 cm is not bigger than 8 m.

A circular swimming pool has a diameter of the 26 feet.
kherson [118]
Hey there! :)

The formula for finding area of circles is: π · r²

<em>Remember that radius is half the diameter. To find radius when the diameter is given, divide by 2</em>

d = 26

26 ÷ 2 = 13
_____________________________________________________________

π · r²

r = 13
13² = 13 × 13 = 169

169 × 3.14 = 530.66 = 530.7

The area of the swimming pool is 530.7 ft²

Hope this helps :)
