Answer:
Step-by-step explanation:
The equation for the area of a circle is A=
.
A=area
r=radius
We were given the diameter of the circle not the radius, so we need to solve for the radius.
Radius=(1/2)Diameter So,
(1/2)6=3mm
Now we can solve for the area.
3^2(3.1415926)=28.2743mm
Now round to two decimal places.
28.27mm
Answer:
13
Step-by-step explanation:
|-20| = 20 (anything with | | is absolute value, which is always positive), |7| = 7, 20 - 7 = 13.
quick tip: when you see something like -|#|, that would be negative, but if you saw |-#|, it would be positive.
hope it helps lol
First you need to find the cicumfrence of the circle which is π × r (radius) or π × c (circumfrance) ÷ 2
Answer:
-7
Step-by-step explanation:
-21.00/3.00
She can ride up with 59 boxes.
Step 1. Subtract Sandra’s weight from the maximum weight. 3,200-145=3,055
Step two. Divide the weight of the boxes by 3,055. 3,055/51=59.9019608
Since she can’t carry .9 of a box, and 60 boxes would be over the maximum weight capacity, Sandra can only ride up with 59 boxes in the elevator.
