Fear not, for Gandalf is here! What you need to do is find the area of the circle. The formula is A = πr2 (pi times squared r). So, in other words, you cut the diameter in half (5 ÷ 2 = 2.5 feet) and do this: 2.5 × 2.5 (this is the squared 2.5). Next, you multiply the factor (which is 6.25) by 3.14. So, you get 19.623, also known as 19.6 if you're rounding to the nearest tenth. Ciao!

Answer:
a = 7
Step-by-step explanation:
The Pythagorean theorem tells you the value of 'a' is ...
a^2 = b^2 - c^2
a^2 = 25^2 -24^2 = 625 -576 = 49
a = √49 = 7
The length of side 'a' is 7 units.
The longer side is at first 7cm and the shorter is 2cm.
So since 7cm(the longer side)×5=35cm then the shorter side(2cm) multiplied by 5 should give you the right answer.
