R is inversely proportional to A.

Mathematics
1 answer:
kow [346]3 years ago
8 0

Answer:

R = 40

A= 1.125

Step-by-step explanation:

12(R) ÷1.5(A) =8

1.5(A) x 8 = 12(R)

1.5(A) x 8 = 12(R) 12(R) ÷ 8 = 1.5 (A)

for 1.5 = 12, you need to times 8

A = 5 and you want to get to R so you times by 8

5 x 8 = 40 | R = 40

R = 9

9 ÷ 8 = 1.125

A = 1.125

We need to compute the diagonal of yhe square.

d²=7²+7²=49×2cm²

d=7×sqrt(2)=7×1.41=9.87cm.

The diagonal we just computed is the diameter of the circle that contains the square.

Since d=9.87 < 11, then indeed, the square fits inside the circle, without touching it.
