The answer is b. 25.12
because we are finding the amount of rope to go around the circle, we are looking for the circumfrence of the circle, and the formula for the circumfrence of the circle is diameter(pi). because the radius of the circle is 4 inches, the diameter iss 8 inches because the diameter is 2(radius) and using multiplication, we can find the the circumfrence to be 25.12 inches
Answer: the last one
Step-by-step explanation:
80 is correct each of the triangles are 2x2/2 therefore 1 triangle is 2 multiples by 4 so all triangles equal to 8 units. The rectangles are 6 by 2 so 6 multipled by 2 multiplied by 2 again because there are 2 rectangles is 24. 8+24=32. Middle section is 8x6 and that equals to 48. 48+32 is 80 therefore the area of this figure is 80 units
12 square centimeters
Step-by-step explanation:
You just multiply the length x the width which is just 3 x 4
Answer:
12.25 and 12.6 per hour
Step-by-step explanation:
For number 2, you take the amount of cookies, x, and divide it by the number of hours, a, and you get x / a = 12.25 or 12.6
For number 3, you do the same as in number 2, you take the pages read, x, divided by the time, a, and get x / a = s
s = 2 and 0.5
