Answer:
Let R = radius of big circle
r=radius of small circle
A1=Area of small circle
A2=Area of big circle
R=9r
A1=50cm^2
A1=pi*r*2
A2=pi*R^2
A2=pi*(9r)^2
A2=81*pi*r^2
A2=81*A1
A2=4050cm^2
Hence the big circle has area of 4050cm^2
Step-by-step explanation:
Answer:
n = 0
Step-by-step explanation:
Let's solve for n, according to the linear equation given, this way:
10n + 0.3 = 0.1n + 0.3
10n - 0.1n = 0.3 - 0.3 (Like terms)
9.9n = 0
n = 0/9.9
<u>n = 0</u>
