First we calculate the area of each semicircle (half the area of the full circle)
and we substract them to get the area of the curved shaded part
1/2 * [ pi * (80/2)**2 ] - 1/2 * [ pi * (60/2)**2 ] = (800-450)pi = 350*pi m2
the area of the full circle (both sides) ------------2*350*pi m2--750*pi m2
The area of the straight line = 2 * (100 *10) = 2000 m2
Total Area = 2000 +700*pi m2 = 4198 m2
Answer:
-3/5
Step-by-step explanation:
50 millimeters is your answer
Answer:
5
Step-by-step explanation:
this is basic algebra so it's important to understand this concept now. you need to combine like terms so 3x-6=9 becomes 3x=15 (you add the 6 to add like terms). You then divide the 3 from 3x on both sides to get x=5
