How much bigger is the area of a quadrant of radius 8 cm than a semicircle of a diameter 4 cm?
Twice as big.
How do you find the area of a rectangle inside of the enclose semicircle if the diameter is 28cm?
It can have any value up to 392 square cm.
How do you find the area of a semi-circle if you know the diameter?
A semicircle is 1/2 of a circle. Find the area with the diameter you are given as if you had a whole circle, then divide that answer by 2 to get the area of the semicircle.
How do you find the perimeter of a semicircle if its diameter is 45 cm?
Perimeter of the semicircle including its base: 180/360*pi*45+45 = 115.686 cm rounded to 3 decimal places
What is the area of a semicircle whose radius is 5 cm?
50.25cm
Area of a semicircle with a diameter of 8 cm?
25
How much bigger is the area of a quadrant of radius 8 cm than a semicircle of a diameter 4 cm?
Twice as big.
What is the area of a semicircle if the diameter is 8 cm?
It is: pi*4^2 divided by 2 = 8/pi which is about 25 square cm
How do you find the area of a rectangle inside of the enclose semicircle if the diameter is 28cm?
It can have any value up to 392 square cm.
What is the perimeter of a 8cm semicircle?
8*pi + 16 = 41.13 cm (approx)It depends on whether 8 cm is the radius or diameter of the semicircle.
How do you find the area of a semi-circle if you know the diameter?
A semicircle is 1/2 of a circle. Find the area with the diameter you are given as if you had a whole circle, then divide that answer by 2 to get the area of the semicircle.
What is the diameter of a semicircle?
In a semicircle, the diameter is the straight line. It is also equal to double the radius, and that property allows it to be used when calculating area and circumference.
What is the area of a semicircle with a diameter of 77 centimeters?
2328.31286 cm2
How do you find the perimeter of a semicircle if its diameter is 45 cm?
Perimeter of the semicircle including its base: 180/360*pi*45+45 = 115.686 cm rounded to 3 decimal places
What is the area of a semicircle whose radius is 5 cm?
50.25cm
How do you find out the area of a semicircle of diameter 20cm?
Area of circle is pi r^2, in this case approx 314 sq cm (3.14 x 10 x 10). For your semi-circle, half of this ie 157 sq cm
What is the approximate area of a semicircle with a diameter of 22 inches?
A semicircle is half a circle, so its area is half that of a circle: radius = 1/2 diameter = 22 ÷ 2 = 11 area = 1/2πr2 = 1/2π112 ~= 190 sq in
