the area of a circle is 28pi cm^2. find the area of a circle with a radius half the length of the original circle.
Verdich [7]

Answer:

The area of circle with radius half of original circle is 7 π  cm² .

Step-by-step explanation:

Given as :

The Area of original circle = 28 π square centimeter

Let The radius of original circle  = R

Let The area of circle with radius half of original circle = A square centimeters

Let The radius of circle with radius half of original circle = R'

Now, According to question

∵ Area of original circle =  π × radius²

So, 28 π cm² = π × R²

Or, R² = \frac{28\times \Pi }{\Pi }

Or, R² = 28 cm²

∴  R = \sqrt{28} cm

i.e R = 2 \sqrt{7} cm

So, The radius of original circle = R =  2 \sqrt{7} cm

<u>Again</u>

∵ The radius of circle with radius half of original circle = R'

So, R' = \dfrac{R}{2}

i.e  R' = \frac{2\sqrt{7}}{2}

∴  R' =  \sqrt{7} cm

So, The area of circle with radius half of original circle =  π × R'²

i.e A = π × R'²

Or, A = π ×(\sqrt{7}) ²

or, A =  π × 7

So, The area of circle with radius half of original circle = 7 π  cm²

Hence The area of circle with radius half of original circle is 7 π  cm² . Answer

Len [333]

Answer:

20

Step-by-step explanation:

if their ages total is 60 and gabrielle's is two times mikhail's age, that means that Mikhail would be twenty because their age times 2 would be 40 and 40 plus 20 is 60.

Which of the following is an extraneous solution of sqrt 4x + 41 = x+5
stiv31 [10]

Answer:

x=-8

Step-by-step explanation:

\sqrt{4x+41}=x+5

on squaring both sides

4x+41=(x+5)^2\\\\4x+41=x^2+10x+25\\\\x^2+6x-16=0\\\\x^2+8x-2x-16=0\\\\x(x+8)-2(x+8)=0\\\\(x-2)(x+8)=0

either x-2=0  or  x+8=0

either x=2 or x=-8

Putting x=2 in original equation, we get

\sqrt{4\times 2+41}=2+5

7=7 hence, it is not an extraneous solution

Putting x=-8 in original equation

\sqrt{4\times (-8)+41}=-8+5

i.e. 3=-3

Hence, x=-8 is an extraneous solution (since it doesn't satisfy the original equation)
