The face of a clock has a circumference of 63 in. What is the area of the face of the clock?

ryzh [129]

Answer:

The area of the clock $= 315.41\ inch^{2}$

Step-by-step explanation:

We have been given the face of the clock that is $63\ in$

So that is also the circumference of the clock.

Since the clock is circular in shape.

So $2\pi(r)=63\ inch$

From here we will calculate the value of radius $(r)$ of the clock that is circular in shape.

Then $2\pi(r)=63\ inch =\frac{63}{2\pi} = 10.02\ in$

Now to find the area of the clock we will put this value of (r) in the equation of area of the circle.

Now $\pi (r)^{2}=\pi(10.02)^{2}=315.41\ in^{2}$

So the area of the face of the clock = $315.41\ in^{2}$

If anyone can help me answer this it would be great thx

zzz [600]

Ok so remember
area=pir^2
area=256pi

256pi=pir^2
divide both sides by pi
256=r^2
squaer root
16=r

find r and d
d=2r
d=2(16)
d=32

radius=16ft
diameter=32ft

If there 10% of a 60ml bottle is filled with antifreeze, how much antifreeze (ml) was in the bottle? If 50% of a 20ml bottle is

miss Akunina [59]

Answer:

Part A: 6ml of antifreeze

Part B: 10ml of antifreeze

Step-by-step explanation:

10% of 60ml is 6ml

60/10 = 6

1/10 of 60 equals 6ml.

50% of 20ml is 10ml.

20/2 = 10

1/2 of 20 equals 10ml.
