First, find the area of the whole square.

Area= Base times height= 48 times 96 = 4608

Next, find the area of ONE circle. The diameter is 12, so the radius would be 6

A=πr sqaured= 3.14 times 6 squared = 113.04

Next multiply by 3, since there are 3 circles.

113.04 times 3 =339.12

Subtract this value from the total area (4608)

4608-339.12=4268.88

ANSWER: 4268.88

Which number has the prime factorization 5 · 72 · 32?
lubasha [3.4K]

Answer:

see below

Step-by-step explanation:

5*72*32 is not a prime factorization to begin with because neither 72, nor 32 are primes. A prime factorization for this product would be:

2*2*2*2*2*2*2*2*3*3*5

and the number with this factorization is 11520.

There is a small chance that what you meant to write was this: 5\cdot 7^2 \cdot 3^2 in which case the number for this prime factorization is 2205.
