Question

Part 4. NO LINKS!! Find the area of the shaded area shown. SHOW WORK PLEASE !! #21​

Answer 1

Area of square

• 32²
• 1024

Radius of each circle

• 32/4/2
• 8/2
• 4

Area of 16 circles

• 16πr²
• 16π(4)²
• 16π(16)
• 256π
• 803.8cm²

Area of shaded region

• 1024-803.8
• 220.2cm²

Answer 2

Area of Shaded

Find the area of the shaded area shown.

Solution:

• A = s²
• A = 32cm
• A = 32cm x 32cm
• A = 1024
• A = 32/4/2
• A = 32 ÷ 2
• A = 8
• A = 8 ÷ 2
• A = 4

So in the inscribed circle there are 16.

• A = 16 radius ²
• A = 16 x 4r²
• A = 4 x 4
• A = 16
• A = 16π x 16
• A = 256π
• A = 256 x 3.14
• A = 803.84
• A = 1024cm - 803.84
• A = 220.16cm²
