Answer:
222.51 (when rounded)
Step-by-step explanation:
Pi x r squared is the formula to find the area of a circle
153.94 + 12.57 + 56
= 222.51
You basically find the area of each circle by find their diameters. So half of the length shown on each circle.
Answer:
Option 2.
Step-by-step explanation:
You are bisecting angle BAC with pencil and compass.
Answer:
(x-3)(x^2-7) = x^3 -3x^2 -7x + 21
just change the sign of the root and put x in front of it, then multiply the factors all together
(x-3)(x-sqr7)(x+sqr7) roots come in conjugate pairs to eliminate irrational coefficients
(x-sqr7)(x+sqr7) = x^2-7. similar to (a-b)(a+b) = a^2-b^2
Step-by-step explanation:
Hey
Area of first rectangle = 18 x 21 = 378 in^2
Area of second rectangle = 17 x 9 = 153 in^2
Total area = 378+153 = 531 in^2
Option 1
Hope this helps :)
