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

A glass marble has a diameter of 18 millimeters. What is the approximate volume of the marble? Use 3.14 for .

maria [59]

The volume of the sphere is 3,052.08 cubic millimeters. The correct answer is A.

<h3>What is the volume of sphere?</h3>

If the given sphere is of radius r units, then its volume is given as:

$V= \dfrac{4}{3} \pi r^3 \: \rm unit^3$

A glass marble has a diameter of 18 millimeters.

The radius is 9

$V= \dfrac{4}{3} (3.14) (9)^3 \: \rm unit^3\\\\V = 3,052.08 cubic millimeters$

The volume of the sphere is 3,052.08 cubic millimeters. The correct answer is A.
