Answer:

Area of rectangle = 448

Area of semi circle = 402.1

Total area = 850.1

Step-by-step explanation:

Area of rectangle = length times width

Given length = 32 cm

Given width = 14 cm

Area = 32 * 14 = 448

Area of semi circle = πr² /  2

where r = radius

Given diameter = 32cm

To convert diameter to radius simply divide by 2

32 / 2 = 16

So radius 16

now we plug 16 into the formula

A=\frac{\pi 16^2}{2} \\16^2=256\\256\pi =804.25\\\frac{804.25}{2} =402.12\\A=402.1(rounded)

Total area = area of semi circle plus area of rectangle

total area = 402.1 + 448 = 850.1

Answer:

Solution given:

length [l]:diameter [d]:32cm

breadth [b]:14cm

radius [r]=32/2=16cm

Area of semi circle:½πr²=½*πx16²=<u>402.12cm</u>²

<h2>+</h2>

Area of rectangle:l*b=32*14=<u>448cm</u>²

<h2>=</h2>

Total area =402.12cm²+448cm²=<u> </u><u> </u><u>850.12cm²</u>

Prove by factorization √16×81=√16×√81
Oksanka [162]

Answer:

√16×81 = 4×9 or √1296 = 36

√16×√81 = 4×9 = 36

Step-by-step explanation:

√81×16

We simplify 81 and 16 by prime factorisation (expressing a number as a product of its prime factors).

√81 = √3×3×3×3 = √9×9 = √9² = 9

√16 = √2×2×2×2 = √4×4 = √4² = 4
