Answer:
Option D : 32.15 square centimeters is the correct answer.
Step-by-step explanation:
Given that:
Area of the circle can be find by the following formula.
Area of circle = pi * radius * radius
The radius of circle in the given figure is 3.2 cm
Area of circle = 3.14 * 3.2 * 3.2
Area of circle = 32.1536 square centimeters
Rounding off to two decimal places.
Area = 32.15 square centimeters
Hence,
Option D : 32.15 square centimeters is the correct answer.
Answer:
Step-by-step explanation:
In order to find the area of this shape, we need to break it up into to distinct shapes: a triangle and a rectangle
We know that the base and height of the triangle are each 6 inches and that the base of the rectangle is 6 inches and the height is 11 inches
The area of this shape is
Answer:
x=9
Step-by-step explanation:
All measurements of the interior angles equals up to 180 degrees when added together, therefore add them all together and set it equal to 180.
7x+2+4x+7+8x=180
-Combine like terms
19x+9=180
-Subtract 9 on both sides
19x=171
-Divide by 19
x=9
Try 3 because 3 times 3 is. 9
