LA = perimeter of base x height
Use Pythagorean theorem to find the base
4^2 + 6^2 = 52
Sq root of 52 is 7.2111...
4+6+7.2 = 17.2
17.2 x 8
137.6 is your answer
Answer:
21.46 cm²
Step-by-step explanation:
because the question want only for the SHADED REGION but NOT AREA OF THE SQUARE
(if we just multiply 10x10. you will get the area of a square which is hundered)
To find the shaded region:
1. area of a circle is πr² (we have 4 circle there)
2. Find the area of all circle
# how do we know the radius?
- half of 10 is 5
- 5 is the diameter of each circle
- the radius is half of 5 which is 2.5
- π(2.5)² = 25/4π (area of 1 circle)
3. since we have 4 circle then, 25/4π x 4 = 25π
4. the area of the square is 100cm²
5. we want the shaded region so we have to minus the area of the circle
6. 100 - 25π (use your calculator to find the answer)
answer should be 21.46 cm²
(hope this helps)
Let's compare!
Taylor ran 57 + 48 mins total. Sum would be 105 mins.
Mark ran 62 + 53 mins total. Sum would be 115 mins.
Clearly, the two sums are different when we compare them using subtraction.
115 - 105 = 10. Mark ran 10 mins longer than Taylor.
Answer:
Explanation:
4x + 2x = 180 degree
6x = 180
x = 180/6
x = 30
Therefore, x = 30 degree
