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

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 diameter of a semicircle when radius is given?
The diameter of the semicircle will be twice the radius.
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 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.
How do you find the circumference of a semicicle?
circumference of a semicircle = pi * diameter / 2 (pi multiplied by the diameter and divided by 2)

How do you find the radius of a semicircle?
it is have the diameter
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 we find a perimeter of a semicircle?
It is its diameter plus half of its circumference
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.
How do you find the distance around a semicircle?
It is half the circle's circumference plus its diameter.
How do you find the circumference of a semicicle?
circumference of a semicircle = pi * diameter / 2 (pi multiplied by the diameter and divided by 2)
What is the formula to find the area of a semicircle?
Pi*radius squared is how to find the area of a semicircle
What is the area of the semi circle 30 feet?
Is the 30ft the radius or the diameter. The area of a circle = Pi x (radius squared), so, if the diameter is 30ft, making the radius 15ft, the area would be Pi x(15 squared) square feet, and the area of its semicircle would be half of that, so the area required = Pi x (15 squared) divided by 2 = 353.429 sq ft On the other hand, if the diameter is 15ft, making the radius 7.5ft then the area required = Pi x (7.5 squared) sq ft for the full circle and half as much for the semicircle = 88.3573 sq ft As an extra; you will find that the area of the smaller semicircle is exactly one quarter of that of the larger semicircle, and I wonder if you can reason out why that is so.
How would you find g field which produces semicircle using equation of semicircle and y?
semicircle PQR of diameter 10 cm.semicircle PAB and BCR of diameter d1 and d2 respectively are inscribed in the semicircle PQR or such that the sum of d1 and d2 is equal to 10 cm. determine the relation between the lengths of arcs PQR,PAB, and BCR.
If diameter is 7 find perimeter of semi circle?
Pi times the diameter gives you the circumference. Then divide that answer by two. Then add in the diameter - and, voila, you have your answer as to the perimeter of a semicircle.
