Surface Area= 2(area of the base)+ Lateral Surface Area Surface Area= 2(3.14(pie) times 36)+ Perimeter of the Base(3.14(pie)times12)8
Surface Area= 226.08+301.44=527.52 meters2
S.A=527.52 meters2

What does the radius of a circle measure?
Half the diameter of a circle called the semicircle
Why isn't the surface of a hemisphere not half the surface area of a sphere?
The surface area of a semicircle has the round surface which is half a sphere and also has the flat surface which is a circle.
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
What is the formula for the perimeter of a semicircle?
If you are given the diameter 'D' of the circle: the full circumference is (pi times D) the perimeter of the semicircle is half this plus the diameter Therefore: Pi x D /2 + D
How many equal length sides does a semicircle have?
None A semicircle is the shape of a protractor (or half a pizza). It has one straight side and one longer curved edge.
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 diameter of a semicircle with a radius of 5 ft?
Radius is = to half the diameter so.... when the radius of the semicircle is 5ft then the diameter is 10ft.
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 we find a perimeter of a semicircle?
It is its diameter plus half of its circumference
How do you find the circumference of a half circle if you have the diameter?
The length of the curved part of the semicicle is π*d/2 where π is the transcendental number approximated by 3.14159 and d is the diameter. The length of the straight part of the semicircle is, of course, d.
What does the radius of a circle measure?
Half the diameter of a circle called the semicircle
How do you find the distance around a semicircle?
It is half the circle's circumference plus its diameter.
Why isn't the surface of a hemisphere not half the surface area of a sphere?
The surface area of a semicircle has the round surface which is half a sphere and also has the flat surface which is a circle.

What is the perimeter of a semicircle with 28mm as diameter?
Perimeter (or circumference) of a circle = pi x diameter = pi x 28, but we need the circumference of only half of it (semicircle is half of a circle) Hence the answer is pi x 14 = 3.1415 x 14 = 43.981 mm
The length of a radius is how many cm the length of a diameter?
The length of a radius is half the length of a diameter.
