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 base of a rectangular prism?
12 the base times the height
How do you find the perimeter of an isosceles triangle when you only have one side and the base?
If you mean "isosceles" triangle, the perimeter is the sum of twice the known side plus the base.
What is the formula for surface area of a pyramid?
Total surface area= 1/2 times the perimeter of the base times the slant height plus the area of the base Lateral surface area= 1/2 times the perimeter times the slant height
What is the perimeter of a rectangle with base 12 and height 6?
It is 36 units.
How do you find the perimeter of of base?
To find the perimeter of the base, you must add all the numbers on the base together!
How do you find the height of a rectangle with the base and perimeter given?
Height = (Perimeter/2) - Base
How you find the area of a rectangle from the perimeter and base length?
perimeter (P)=2(length+base) find length, area = length * base = (p/2-base)*base
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 out the measurement of the perimeter of a rectangle?
2*(base) + 2*(height) = perimeter
If the base of a triangle is doubled how does the perimeter change?
If the base of a triangle is doubled while the other sides remain unchanged, the perimeter of the triangle will increase by the amount equal to the original base length. Specifically, if the original base is ( b ) and the other two sides are ( a ) and ( c ), the new perimeter becomes ( (2b + a + c) ), resulting in an increase of ( b ). Thus, the total perimeter becomes the original perimeter plus the original base length.
How do you find the area of the right angle triangle given the base hypotenuse and perimeter?
It is: perimeter minus hypotenus+base = height Area = 0.5*base*height
How do you find a perimeter of an isosceles triangle?
Assuming that neither of the sides of equal length is the base, Perimeter = Base + 2*Slanted sides.
What is the perimeter formula for a rectangle?
2 x base + 2 x height= perimeter
A triangle has a base of length 20 units and perimeter of 66 units. If a similar triangle has a base of 15 units what is its perimeter?
49.5 units
Why does the choice of the base change the perimeter of a parallelogram?
It does not. The perimeter of a parallelogram is a characteristic of the parallelogram. The orientation: which side is considered a base makes do difference whatsoever.
If the base of an isosceles triangle is 11 and the perimeter is 39 what is the length of a leg?
If the base of an isosceles triangle is 11 and its perimeter is 39, then it has a height of 12.87.
