All points in a plan 4 units from point P
that is a circle
defenition is the set of all points the same distance from a given point
CIRCLE
Answers:
- first blank = not sure (see explanation below)
- second blank = 3*sqrt(6)
- third blank = 3pi
============================================================
Explanation:
Use your calculator to compute 3*sqrt(6) = 7.348469 which is approximate.
We can see that 3*sqrt(6), aka 7.348469, is between 7 and 9
Do the same for 3pi to get 3pi = 9.424778 approximately. So this goes between 9 and 11
As for the first blank, between 5 and 7, it seems like an answer choice is missing. So I would ask your teacher about that. If your teacher meant it to be left blank, then just ignore it.
Answer:
35 m²
Step-by-step explanation:
Given:
- length of each side of the square compost heap = 1.2 m
- ratio of compost heap side length to hedge length = 2 : 11
⇒ length of hedge = (1.2 ÷ 2) x 11 = 6.6 m
Given:
- length of gate = 2m
- length of gate is 1/4 length of pond
⇒ length of pond = 2 x 4 = 8m
Given:
- area of pond = 28 m²
- length of pond = 8 m (from previous calculation)
⇒ width of pond = 28 ÷ 8 = 3.5 m
⇒ perimeter of pond = 2 x 8 + 2 x 3.5 = 23 m
Given:
- length of pond = 8 m
- length of gate = 2 m
⇒ length of flowerbed = 8 + 2 = 10 m
Given:
- length of flowerbed = 10 m
- perimeter of flowerbed = perimeter of pong = 23 m
⇒ width of flowerbed = [23 - (2 x 10) ] ÷ 2 = 1.5 m
Area of grass = (length of gate x width of pond) + (length of flowerbed x [length of hedge + length of compost heap - width of flowerbed - width of pond])
= (2 x 3.5) + (10 x [6.6 + 1.2 - 1.5 - 3.5])
= 7 + (10 x 2.8)
= 35 m²

Answer:
see explanation
Step-by-step explanation:
note that 3.28 = 2 × 1.64
This could be a geometric sequence with common ratio r = 2
To obtain the next term multiply the previous term by 2
3.28 × 2 = 6.56
6.56 × 2 = 13.12
1.64, 3.28, 6.56, 13.56 ← first 4 terms in sequence
