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:
192cm³
Step-by-step explanation:
12cm * 4cm * 4cm
width times length times height
Answer:
≈ 763.41
Step-by-step explanation:
I am in a very young grade, so tell me if i'm wrong. I'm sorry if I am...
Volume of a cylinder: πr^2h
So: π * 4.5^2 * 12
V≈763.41 millimeters
Can you elaborate? because i don’t understand what topic
Joan = H
so to get Gill's height subtract 3
Gill's height = H - 3
