12.56. The formula for the area of a circle( radius squared time pie) No, when u double the radius the area quadruples because your squaring the radius.
Answer:4128 and 4293
Step-by-step explanation:
8421-165=8256
8256/2=4128
4128+165=4293
4293+4128=8421
Answer:
1.a
2.e
3.e
Step-by-step explanation:
When you multiply 13.75 and 20.5 together, you get 281.875
You will want this equation to be in y=mx+b, because you already have the slope and y-intercept. X will be the number of days she has had the plant, and Y will be the height of the tree, because it is the variable being affected by the X. The slope, or the M, is 2.5 because this is the number of centimeters the tree grows per day. The y-intercept is 5, because this is the height of the tree originally. So, the equation is Y=2.5X+5. To solve the number of days Margo will have had the plant, plug in 65 (the height of the plant after a certain amount of days) into the Y variable and solve for X. So, 65=2.5X+5. Subtract 5 from both sides to get 60=2.5X, then divide both sides by 2.5 to get X=24. So, she will have owned the plant for 24 days.
