What is the area of a figure formed using a semicircle with a diameter of 16 feet and a trapezoid with a height of 8 feet and bases of 12 feet and 14 feet?
To find the area of the figure, we first need to find the area of the semicircle and the trapezoid separately, then add them together. The area of a semicircle is half the area of a full circle, which is πr^2, where r is the radius. In this case, the radius is half the diameter, so 16/2 = 8 feet. Therefore, the area of the semicircle is 1/2 * π * 8^2 = 32π square feet. The area of a trapezoid is calculated using the formula A = (1/2) * (b1 + b2) * h, where b1 and b2 are the lengths of the bases and h is the height. Plugging in the values, the area of the trapezoid is (1/2) * (12 + 14) * 8 = 104 square feet. Adding the areas of the semicircle and trapezoid together gives a total area of 32π + 104 square feet.
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
What is area of semicircle?
The area of a semicircle is half of the area of a circle. The area of a circle is pi x radius x radius. So the area of a semicircle is 1/2 x pi x radius x radius or (pi x radius x radius) / 2.
What is the area of a semicircle when the radius is 21?
The equation for area of a circle is A=pi x R x R. A semicircle is half a circle, so we calculate the area of a circle and divide by 2. The area of the circle would be approximately 1384.74. Thus the area of the semicircle would be 692.37.
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 formula to find the area of a semicircle?
Pi*radius squared is how to find the area of a 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 area of a 12 inch semicircle?
Area in square inches = (pi*radius^2)/2
What is the area of each semicircle to the nearest square meter?

Calculate the area of semicircle with radius 4 meters?
An area of a circle is pi*r2 - so an area of a semicircle is 0.5*pi*r2: 0.5*3.14*42 = 25.13 square meters
A Norman window has the shape of a semicircle atop a rectangle so that the diameter of the semicircle is equal to the width of the rectangle. What is the area of the window with a perimeter of 45 feet?
To find the area of the Norman window, you need to divide the perimeter by 2 to get the width of the rectangle, which is 22.5 feet. The radius of the semicircle is half of the rectangle's width, so it's 11.25 feet. The area of the rectangle is 11.25 * 22.5 = 253.13 square feet, and the area of the semicircle is 0.5 * pi * 11.25^2 = 198.93 square feet. So, the total area of the window is 253.13 + 198.93 = 452.06 square feet.
What is the equation to solve the area of a semicircle?
Area of a semicircle = (pi*radius^2)/2

How do you find the area of a rectangle with a semi circle attached to it?
Calculate the area of a rectangle and of the semicircle separately, then add.
How do you find the area of a semi-circle radius 10cm?
πr² is the formula for finding the area of a circle. To find the area of a semicircle just divide the answer by two. So take the radius, square it, which in this case would be 100, multiply it by π [pi (3.14)] and divide it by two.
If the diameter of a pizza was 50cm and it was a perfect semicircle what is the area of the smallest square box in square centimetres that could contain the half pizza?
