Answer:
10
One tank is 25 buckets of water, so 2/5 of a tank is 10 buckets of water.
Answer:
2/5
Step-by-step explanation:
in 4/10, both the numerator (4) and denominator (5) are multiples of 2, as 4 = 2 * 2 and 10 = 2 * 5. thus, we can divide both the numerator and denominator by 2 to get
(4/2) / (10/2) = 2/5 as our answer.
Answer:
Step-by-step explanation:
<u>Given </u>
- Square of 8 cm and part of the circle of same radius
<u>Perimeter of the shape is sum of two quarter circles:</u>
<u>The area is calculate as follows:</u>
Half of the area of the shape is the difference of the quarter-sector of the circle and half-area of the square
- 1/2A = 1/4πr² - 1/2*8²
- A = 1/2π*8² - 64 = 32π - 64
- A = 32π - 64
