As stated the area of the circle is 85π ft2. The area of the sector BAC is a portion of this full circle area. the sector is made of 2 radii and arc that has rotated by 36°.
the magnitude of the central angle in the circle is 360°
Area for 360° central angle - 85π ft2
then the area for 1° = 85π ft2/360°
the area of 36° sector = 85π ft2/360° x 36°
= 8.5π ft2
Answer: 5
Step-by-step explanation:
use formula a^2 + b^2 = c^2
a^2 + 12^2 = 13^2
a^2 + 144 = 169
- 144 -144
a^2 = 25
sqrt sqrt
a = sqrt (25)
a = 5
