?%= 75%
Answer:
![173.21cm^2](https://tex.z-dn.net/?f=173.21cm%5E2)
Step-by-step explanation:
![A=\frac{\sqrt{3} }{4} a^2\\P=3a\\](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B%5Csqrt%7B3%7D%20%7D%7B4%7D%20a%5E2%5C%5CP%3D3a%5C%5C)
Solve for A
![A=\sqrt{3} \frac{P^2}{36} \\=\sqrt{3} *\frac{60^2}{36} \\=173.21cm^2](https://tex.z-dn.net/?f=A%3D%5Csqrt%7B3%7D%20%5Cfrac%7BP%5E2%7D%7B36%7D%20%5C%5C%3D%5Csqrt%7B3%7D%20%2A%5Cfrac%7B60%5E2%7D%7B36%7D%20%5C%5C%3D173.21cm%5E2)
All three triangles are congruent by SAS
Answer:
r = 1.499619733762 m There is no such thing a quarter radius!
C = 9.4223886775301 m
A = 7.065 m^2
Step-by-step explanation:
Calculate r and C | Given A
Given the area of a circle calculate the radius and circumference
r = √(A / π)
C = 2πr
Agenda:
r = radius
C = circumference
A = area
π = pi = 3.1415926535898
√ = square root
B) 154, 171, 188, 205, 222
A constant value (17) is added to get the next number
