Answer:
20 girls.
Step-by-step explanation:
If 32 divided by 8 is 4, then 4x8= 32.
We use this equation to find out how many girls there are. 5x4 equals 20, so there are 20 girls at summer camp.
The area of the circular shaped patio is: 172.7 ft²
<h3>What is the Area of a Circle?</h3>
Area of a circle = πr² [r is given as the radius of the circle].
The area of the patio = area of the larger circle - area of the smaller circle.
Radius of the larger circle = 8 cm
Radius of the smaller circle = 3 cm
π = 3.14
Area of smaller circle = πr² = (3.14)(3²)
Area of smaller circle = 28.26 cm²
Area of bigger circle = πr² = (3.14)(8²)
Area of bigger circle = 200.96 cm²
The area of the patio = 200.96 - 28.26
The area of the patio = 172.7 ft²
