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 :)
11.424242
isolate the repeating part
11+0.424242
focus on the repeating part
0.42424242
how many places till it repeats again?
2
let's say it is x
x=0.42424242
multiply by 100
100x=42.424242
subtract them
100x-x=42.42424242-0.42424242
the infinite repeats cancel and we get
99x=42
divide by 99
![x=\frac{42}{99}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B42%7D%7B99%7D)
so
Answer:
4pi
Step-by-step explanation:
Circle circumference = 2*pi*r
2*pi*2
4*pi
Multiply 3x9 and it gives u 27
And -3 plus -9 equal -12
