Anybody know the area of a quarter if the diameter is 2.5cm??

Answer 1

Area of circle = π r^2 = π (2.5/2)^2 = 1.5625π cm^2.
Area of quarter = above area / 4 = 0.390625π cm^2

Answer 2

a ten year previous quarter horse is one in all the equivalent of a 20-30 year previous human - would desire to a guy or woman of this age learn a sparkling self-discipline? honestly - at 10, the pony is now mature sufficient to have settled in and be listening - so if he's sound sufficient for easy artwork, he's honestly bodily in a position to do dressage. i understand many, many quarter horses that do dressage. they variety plenty in physique layout, some are confusing to tell they do no longer look to be a heat-blood breed. a stable factor of the common quarter horses have some quantity of Thoroughbred blood in them so have a tendency to be long and lanky like a classic dressage horse would seem. I even have 2 TB Paint mare sisters - their TB area is thru racing traces and their paint area is thru QH racing traces. They ended up tall and geared up properly for Dressage. i've got theory approximately getting to know myself yet i'm no longer the slightest bit knowledgeable approximately English driving. that's totally in all probability the pony in question would be a stable candidate for dressage. They key lies extra in what and how he's been experienced and how properly he's dealt with now to despite if he would be victorious at dressage or no longer and in what quantity of time.

Answer 3

If the diameter is 2.5, then the radius is 1.25
Use the formula A=pi*r^2 to get the answer.

Answer 4

where pie=22/7, area of a circle is A=22/7r^2

diameter is equal to 2 times the radius, so the radius is diameter divided by two, therefore r=1.25

So
A=(22/7)(1.25^2)
area is approximately 4.911

Answer 5

a quarter? the coin? if so, then radius is half the diameter - 1.25cm. Area = pi*(r^2)=pi*(1.25)^2. I dont have a calculator. also, depends if you include the width. if so, then multiply by the answer by the width. thats the standard area.

Answer 6

area of a circle=pi*r^2 (r=d/2)
=22/7*1.25*1.25
=4.90625 cm2
and you want to consider area of both sides of quarter multiply it by 2=4.90623*2=9.8125

Answer 7

Area of a circle formula

C = πr²

-- - - - - - - - - - - - - - - - - - - - - - - -

First divide the diameter in half

2.5 ÷ 2 = 1.25cm

1.25 cm is the radius

C = (3.141592654)(1.25)²

C = 3.141592654(1.5625)

C = 4.908738521cm

C = 4.9cm rounded to one decimal points

The answer is C = 4.9cm

The solution set is { 4.9 }

Answer 8

area = pi *(diameter/2) ^ 2

Answer 9

Area = pi*(d/2)^2 = 4.91 cm^2.

Answer 10

5 of course at least i think
