A - 7 + 3 = 0
a -4 = 0
a = 4
Answer is C
Circumference of the outer circle = 2πr = 2π(6) = 12π
circumference of the outer arc = 120/360 x 12π = 12.57cm
circumference of the inner circle = 2πr = 2π(5) = 10π
circumference of the inner arc = 120/360 x 10π = 10.47 cm
Difference in length = 12.57 - 10.47 = 2.1cm (1 d.p.)
Answer: 2.1cm
Answer:
1250 women
Step-by-step explanation:
m 6. 1500
w 5. x
so 1500 ×5 gets u 7500 then divide that by 6 then u get 1250
Answer:
<u>7</u>5,575 - ten-thousands place; this 7 is worth 70,000
7<u>5</u>,575 - thousands place; this 5 is worth 5,000
75,<u>5</u>75 - hundreds place; this 5 is worth 500
75,5<u>7</u>5 - tens place; this 7 is worth 70
75,57<u>5</u> - ones place; this 5 is worth 5
We determine first the real dimension of the circular fountain by using the scale factor given.
(18 cm) x (4 ft / 3 cm) = 24 ft
Then, calculate for the area of the base of the circular fountain by the equation,
A = πD²/4
where A is are and D is diameter. Substituting,
A = π(24 ft)²/4 = 144π ft² ≈ 452.4 ft²
Thus, the area of the base of the circular fountain is approximately 452.4 ft².
