Answer:
Step-by-step explanation:
The area of the shaded region is:
- The area of circle - area of triangle
Diameter of the circle is the hypotenuse of right triangle. As per Pythagoras:
- d = √20²+21² = √400+441= √841 = 29in
- r = d/2 = 29/2 = 14.5 in
Area of circle:
- A = πr² = 3.14*14.5² = 660.2 in²
Area of triangle:
- A = ah/2 = 20*21/2 = 210 in²
Shaded area:
Answer:
257/2
Step-by-step explanation:
So in condition we need to know π=180 so when you multiply by π/180 or 180/π is one
it says we need to change from radian to degree so we need time 180/π
so it like this:
(257π)/360*(180/π)=257/2.
Answer:
Option B
Step-by-step explanation:
step 1
Find the number of cubes in the prism
step 2
Find the volume of one cube
The volume of one cube is equal to
where
b is the length side of the cube
we have
substitute
step 3
To find out the volume of the prism , multiply the volume of one cube by the number of cubes
so
simplify
Any number as the denominator and 0 as the numerator can be replaced in the place of 0.
Answer:
23/2
Step-by-step explanation:
If x = 5,
y = 5 + 1 = 6
(5+6) + 1/2 = 11 + 1/2 = 23/2
