Answer:
2544 ft
Step-by-step explanation:
First, find the area of the pool.
A= πr²
if we fill in the radius, use 3.14 for pi, and solve for A, that's
A=(3.14)(20.5)²≈1319.585
The area of the pool is roughly 1319.585 ft
Now, we find the area of the triangle
A=(ab)÷2
put in 'a' and 'b' (the triangle legs) and solve
A=(84×92)÷2=3864
Finally, subtract the area of the pool from that of the triangle
3864-1319.585=2544.415 which rounds to 2544 ft
hopefully that helps and you might want to double check but that's what I got :)
Answer:
Step-by-step explanation:
Cameron task: 3/7 × 2/9
What he did:
• Simplify 3/7 to 1/7
• mulitiplied the fractions 1/7 and 2/9
Cameron's error was:
• The "simplification":
To simplify a fraction is to reduce to the lowest possible multiple. Illustration:
Simplify 16/100
= 2/25
But in the case of 3/7, the answer is 3/7.
What Cameron would have done:
1. 3/7 = 2/7 + 1/7
3/7 × 2/9 = (2/7 × 2/9) + (1/7 × 2/9)
= 4/63 + 2/63
= 6/63
2. since he simplified 3/7 to 1/7
1/7 = 3/7 × 1/3
Therefore,
3/7 × 2/9 = 1/7 × (2/9 × 3)
= 1/7 × 6/9
= 6/63
