Answer:
The approximate length of the radius, r is 12 inch.
Step-by-step explanation:
Given:
A circle P is given having circumference C,
C = 75 inch
pi = π = 3.14
radius = r
To Find:
radius = r = ?
Solution:
Circumference:
In geometry, the circumference (from Latin circumferens, meaning "carrying around") of a circle is the (linear) distance around it.
That is, the circumference would be the length of the circle if it were opened up and straightened out to a line segment.
Formula is given as
Substituting the values we get
75 = 2 × 3.14 × r
∴ 
We approximate radius to
radius = 12 inich

Answer:
324 cm²
Step-by-step explanation:
→ Work out perimeter of square
72 + 72 + 72 + 72 = 288
→ Work out the width of the rectangle
288 - (90 × 2) = 108
108 ÷ 2 = 54
→ Work out area of square
72 × 72 = 5184 cm²
→ Work out area of rectangle
90 × 54 = 4860 cm²
→ Minus the areas from each other
5184 cm² - 4860 cm² = 324 cm²
