Answer:
Step-by-step explanation:
When a circle is rolled out, the base becomes πr and the heignt of each cone becomes r, therefore when the circle is made the equation become πr²
<u>Answer:</u>
The area of the shape is 68 cm².
<u>Step-by-step explanation:</u>
We have to calculate the areas of the rectangle and triangle separately, and then add them together.
• Area of rectangle = length × breadth
= 30 cm × 2 cm
= 60 cm²
• Area of triangle = × base × perpendicular height
= × 2 cm × 8 cm
= 8 cm²
Adding the areas together = 60 cm² + 8 cm²
= 68 cm²
X=11 because 35+5x=90 and 90-35 is 55/5=11
