Answer:
The area of the shaded region is 7π square centimeters.
Step-by-step explanation:
Note that Circle B has a radius of 3 cm, and the two smaller circles, Circles O and C, both have a radius of 1 cm.
The area of a circle is given by:

Therefore, the area of Circle B, the entire circle, is:

The area of Circle O is:

And likewise, the area of Circle C is:

The area of the shaded area is the area of the Circle B subtracted by the area of Circles O and C. Hence:

Substitute and evaluate:

The area of the shaded region is 7π square centimeters.
Answer:
y = -1/2x + (-1)
Step-by-step explanation:
D because 5.50 is x and your y so boom D
⇒ s = a+b+c2=5+12+132 a + b + c 2 = 5 + 12 + 13 2 = 15 cm.
Area of the base = √s(s−a)(s−b)(s−c)
= √15×10×3×2 15 × 10 × 3 × 2 cm2 = 30 cm2
Answer:
10
Step-by-step explanation:
x-7=?
x=17
17-7=10
7+10=17
17=17 Correct :)
