Let’s start with the rectangle. 6(4) = 24 cm^2. The triangle is 1/2(bh). We know the bottom of the triangle is 4 because 10-6=4. 4(4) = 16 16/2 = 8 We’re at 32 square cm so far. Now the semi circle. The diameter is 4, so the radius is 2. A = (pi)r^2 A = (pi)4 A= 4pi Best estimate could be expressed as 32 + 4pi cm^2, or substituting 3.14 for pi, 44.56 cm^2
Well, you have to read 10 1/2 pages and you have read 1/3 so ask your self...Self what is 1/3 of 10 1/2 pages. The key word of tells you to multiply the two numbers to find the answer. So
