Answer to your equation is X=8.25
Answer:
13
Step-by-step explanation:
The product of two negative numbers is positive. The absolute value of a number is its magnitude written with a positive sign.
6 -2(-1) +|-5|
= 6 + 2 + 5
= 13
11. The r in this equation stands for the radius, or 2 in this case, and the h stands for the height, or 18 in this case. Therefore, you would substitute these values in to get the equation of V=(1/3)pi(2)(18).
Multiply 2 and 18 together to get V=(1/3)pi36.
Multiply pi by 36, which should give you something around V=(1/3)(113.04).
Now divide 113.04 by 3, which is the same as multiply it by one third, to get 37.68. The volume of this cone is about 37.67 cubic inches.
12. The base of this cone, and all other cones, is a circle. The formula for the area of a circle is A=pi•r^2. This means that the pi•r^2 part of this equation represents the area of the base because that section is the exact same formula for the area of a circle, which is the shape of a cone’s base.
Cut it up
1 trapezoid on top
2 paralellograms on bottom
area of trapezoid=1/2(b1+b2) times h
trapezoid bases are 17 and 7+7
height=8
area=1/2(17+14) times 8
area=124
area of 2 trapezoids
base=14
height=6
area=base times height
14*6=84
times 2 because we have 2 of them
168
add
124+168=292m^2
