Answer:
r = 22 ft the sprinkler sends water until 22 feet away
Step-by-step explanation:
A circular pattern has an area of 1,519,76 ft²
And the areaof a circle is:
A(c) = π*r²
A(c) = 3,14 * r² ⇒ 1,519,76 = 3,14 * r²
r² = 1,519,76/3,14 ⇒ r² = 484
r = √484
r = 22 ft
Let b be the speed of the boat; and c be the speed of the current. Then:
5b-5c=130
5b+5c=220
10b=350
b=35
c=9

Answer:
Answer a: mST=20
Answer b: mST=48
Step-by-step explanation:
Problem a:
3a-5=2a+50
a=55
2(55)+50=160
180-160=20
Problem b:
180=4c-12
192=4c
48=c
Answer:
3 cylinder will fill 9 cones with water
Step-by-step explanation:
This problem bothers on mensuration of slides, cone and cylinder
We know that the
Volume of a cylinder = πr²h
Volume of a cone = 1/3(πr²h)
Given that both cylinder and cone has same height and radius
From the given expression we can deduce that the cone is 3 times smaller than the cylinder in volume
So if 1 cylinder will fill 3 cones
Then 3 cylinders will fill x cones
By cross multiplication we have
x= 3*3cones
x= 9 cones
Hence 3 cylinder will fill 9 cones with water
