Answer:
24
Step-by-step explanation:
14/2=7
25^2-7^2=576
sqrt576=24
Answer:

Step-by-step explanation:
step 1
Find the area of the circle
The area of the circle is

we have
----> the radius is half the diameter
substitute


step 2
Find the area of a sector
Remember that
The area of the circle subtends a central angle of 360 degrees
so
using proportion
Find out the area of a sector with a central angle of 108 degrees

assume

substitute

Answer:
10^2 × 10^2
Step-by-step explanation:
Given that
Write 100 times 100 that would be multiplying to the power by 10
So based on the above information
The equation that would be developed is
10^2 × 10^2
The same would be represented as an answer
Formula for the area of a circle: A = pi * r^2
A semi-circle is half of a circle. So, we will need to divide the area of the total circle by 2 to find the area of a semi-circle.
r = d / 2
r = 6 / 2 = 3
A = pi * 9
A = 9pi
Semi-circle:
A = 9pi / 2
A = 4.5 pi cm^2 or 14.14 cm^2
Hope this helps!! :)
