4 + 8 = 12 that is the answer
What we know:
shape is circular
Area=64π yr²
Area=πr²
circumference=2πr
In order to find circumference we need r=radius. We can use the area to find r by solving for r using substitution of the information we know above.
Area=πr²
64π=πr² substitution
64π/π=π/πr² multiplicative inverse
64=r²
√64=√r² properties of radicals
8=r We would get two solutions, a positive and negative one but we will only use the positive solution since radius is positive
Circumference=2πr
C=2π(8)=16π yards
Answer:
7672.50
Step-by-step explanation:
7500×0.23%=17.25
17.25×10=172.50
7500+172.50=7672.50
The GCF is 2
Pull out 2 from each number:
2(2n + 5)
Hope this helps!
