If the semicircle is adjacent to the square, that means that the semicircle has a diameter equal to the length of the square, which is 32 cm. The formula for the area of a circle is
pi times the radius squared
. Because the diameter of the semicircle is 32, the radius is half of that, or 16.

How do you find the area of a square that can be inscribed?
When a circle is inscribed in a square, the length of each side of the square is equal to the diameter of the circle. That is, the diameter of the inscribed circle is 8 units and therefore the radius is 4 units. The area of a circle of radius r units is A
=πr2
. Substitute r=4 in the formula.
How do you find area?
To find the area of a rectangle or a square you need
to multiply the length and the width of a rectangle or a square
. Area, A, is x times y.
What is the area of quadrant?
The formula of area of quadrant of circle goes by, Area of a Quadrant
= πr
2
/ 4
.
What is the area of the circle that can be inscribed in a square of side 6cm?
36 πcm2
.
What is the area of a circle that can be inscribed in a square of side 8 cm?
radius =8cm diameter = 2*8=16cm . Then let side of square be X so a/q Xsq + Xsq =16 sq so Xsq =
128 cm sq
. It’s your answer.
What is the area of the largest square that can be inscribed?
24 cm2
.
How do I find the perimeter and area?
The perimeter P of a rectangle is given by the formula,
P=2l+2w
, where l is the length and w is the width of the rectangle. The area A of a rectangle is given by the formula, A=lw , where l is the length and w is the width.
How do you find the area of all shapes?
- Square area formula: A = a2
- Rectangle area formula: A = a * b.
- Triangle area formulas: A = b * h / 2 or. …
- Circle area formula: A = πr2
- Circle sector area formula: A = r2 * angle / 2.
- Ellipse area formula: A = a * b * π

What is the area of the quadrant calculator?
- As quadrant is a quarter of a circle, we can write the formula as: Quadrant area = Circle area / 4 = πr2 / 4.
- Quadrant’s central angle is a right angle (π/2 or 90°), so you’ll quickly come to the same equation: Quadrant area = α * r2 / 2 = πr2 / 4.
What is the meaning of quadrant of circle?
quadrant Add to list Share. A quadrant is
one-fourth of a circle
. … When a circle is evenly divided into four sections by two perpendicular lines, each of the four areas is a quadrant.
How do you calculate quadrant?
Now, to calculate the area of a quadrant,
divide the area of a circle by 4
(as four quadrants make a circle). We get, Area of a quadrant, A= (πr
2
)/4 Square units.
What is the area of circle that can be inscribed in a square of side 10 cm?
For inscribed circle: radius=side of square2⇒r1=102=5cm. We know that, area of the circle is given by πr2. So, the area of the inscribed circle is
πr12=π×52=25πcm2
.
What is the area of 6cm circle?
The area of a circle is equal to
Pi π times the radius r squared
. Substitute in the value of the radius r=6 into the formula for the area of a circle. Pi π is approximately equal to 3.14 . Raise 6 to the power of 2 .
