A. To find the area of a circle you need to use the formula A= π r²
The radius (R) is half of the diameter . . . that's 6.5 cm .
r² = (
6.5)² = 42.25 cm²
Area = π r² = 42.25 π = <em>132.7 cm²</em>
B. Area of a rectangle is just (length) x (width).
Length = 12 cm
Width = 5 cm
Area = (12 cm) x (5 cm) = <em>60 cm²</em>
C. The shaded portion is the part of the circle that's NOT in the rectangle. So its area is (area of the circle) - (area of the rectangle)
Area = (132.7 cm²) - (60 cm²) = <em>72.7 cm²</em>
Answer:
x=-6
Step-by-step explanation:
1.distribute
2.add
3.combine like terms
4.Add 12 to both sides
5.simplify
Answer:
13.5 is the next term
4, 6, 9, 13.5
Step-by-step explanation:
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 3/2
formula= an=a1⋅r^n-1
Step 1 Add 2 to both sides.
5x=3+2
Step 2 Simplify 3+23+2 to 55.
5x=5
Step 3 Divide both sides by 5.
x=1
Hoped this helped :)
