<h3>Answer:  980.06 cm²</h3>

Explanation:

We need to find the area of a full circle with radius 10.2 cm

A = pi*r^2

A = 3.14*(10.2)^2

A = 326.6856

This is the approximate amount of area the minute hand covers in 1 hour.

In 3 hours, it covers 3 times that amount.

3*326.6856 = 980.0568

That rounds to 980.06

If a diameter intersects a chord of a circle at a right angle, what conclusion can be made?
drek231 [11]

Answer:

The chord is bisected.

Step-by-step explanation:

see the attached figure to better understand the problem

In the circle of the figure

The diameter is the segment DE

The chord is the segment AB

PA=PB=r ----> radius of the circle

Triangles PAC and PBC  are congruent right triangles by SSS

Because

PA=PB

PC is a common side

AC=BC ----> Applying Pythagoras Theorem

therefore

The chord AB is bisected
