Answer:

Step-by-step explanation:

Simplify the following:

2×6 - 7 + 9^2 + 45/5

What is the area of the red region?

Nitella [24]

Answer:

≈ $57.13cm^{2}$

Step-by-step explanation:

Area of Circle:

$A =$ π $r^{2}$

π $(4)^{2}$

π (16)

≈ $50.27cm^{2}$

Area of Square:

$A = l(w)$

$8(8) = 64 cm^{2}$

Area of each corner:

$64 - 50.27 = 13.73cm^{2}$

13.73 ÷ 4 ≈ $3.43cm^{2}$

Area of Red:

$50.27 + (3.43(2))$ ≈ $57.13cm^{2}$
