What would the perimeter of a 20ft semicircle be?
That depends on what you mean by a "20 ft semicircle".A semi-circle is a half circle.A 20 ft circle could be:A circle of diameter 20 ftThe perimeter of the semicircle is half the circumference plus the diameter → perimeter = 1/2π 20 ft + 20 ft= 10π + 20 ft≈ 51.42 ftA circle of radius 20 ftThe perimeter of the semicircle is half the circumference plus double the radius → perimeter = 1/2 2π 20 ft + 2 x 20 ft= 20π + 40 ft≈ 102.08 ftA circle of circumference 20 ftThe perimeter of the semicircle is half the circumference plus the diameter → perimeter = 1/2 20 ft + 20 ft ÷ π= 10 ft + 20/π ft≈ 16.37 ftHowever, if a 20 ft circle is a circle with a circumference (= perimeter) of 20 ft then a 20 ft semi-circle could be a semicircle with a perimeter of 20 ft→ perimeter = 20 ft
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.
What is the area of a square whose perimeter is 36 inches?
The area of a square whose perimeter is 36 inches is: 81 square inches.
What is the perimeter of the semicircular region 5 inches?
To find the perimeter of a semicircular region with a diameter of 5 inches, you first calculate the radius, which is 2.5 inches. The circumference of a full circle is given by (C = 2\pi r), so for the semicircle, it is (\pi r). Thus, the perimeter of the semicircle is (\pi \times 2.5) inches plus the diameter, which is (2.5\pi + 5) inches. Therefore, the total perimeter is approximately (2.5\pi + 5 \approx 7.85 + 5 = 12.85) inches.
A welcome mat on the front porch is a semicircle. The straight side of the mat is 36 inches. What is the perimeter of the mat?
92.55 inches
If the base of a semicircle is a feet What is its perimeter?
The circumference of a circle = 2π r = π a (where a is the base of the semicircle and is also the diameter of the circle) The perimeter of the semicircle = half the perimeter of the circle + the base length The perimeter of the semicircle = πa/2 + a = a(1 + π /2) feet
How do you find the perimeter of a shape that has a semicircle?
To find the perimeter of the curved section of the semi-circle: Perimeter of semicircle = Pi x radius If you also need to the find the perimeter of the straight part of the semicircle (the diameter), it is simply double the radius.
The radius of the semicircle is 5 feet and the dimensions of the rectangle are 10 ft by 16 ft The semicircle is attached to the width of it What is the perimeter?
Perimeter = (2*pi*5*1/2)+10+16+16 = 57.70796327 or 58 feet
What is the formula of a semicircle in perimeter?
The perimeter of a semicircle with radius R is pi*R + 2*R = R*(pi + 2)
How many inches do you need to cover the semi circle given below if its diameter is 28 inches?
The perimeter of the semicircle is 71.98 inches, approx. The semicircle cannot be covered by any number of inches because an area (in 2-dimensional space) cannot be covered by a length (in 1-dimensional space).
What is the perimeter and area of a semi circle that has a radius of 4 inches?
The circumference of a circle is 2{pi}r. So, for a semicircle it is half this, that is {pi}r. The perimeter of the semicircle is the round bit ({pi}r) plus a diameter of the circle (2r) perimeter = {pi}4 + 2 x 4 ~= 20.6 in Area of a circle is {pi}r2, so for a semicircle it is half this. area ={pi}42 / 2 ~= 25.1 in2.
Perimeter of a semicircle when the Diameter is 8?
Perimeter of a semicircle is the length of the half-circle plus the diameter. The whole circle would have a length of diameter times pi, but since it's only half... Perimeter of semicircle = (1/2*pi*D) + D
What is the perimeter of a triangle with sides 11 inches 5 inches and 13 inches?
The perimeter is 11 + 5 + 13 = 29 inches.
What is the total perimeter of 5 pentagon if each side is 5 inches?
The perimeter of each pentagon is 25 inches.
What is the perimeter of a semicircle with radius 8cm?
A semicircle is half a circle. So the perimeter of a semicircle is half the circumference of the whole circle plus the diameter, which is twice the radius: perimeter = 1/2 x 2{pi}r + 2r perimeter ~= 3.14x8 + 2x8 ~= 41.13cm
