Answer:
27 / 28
Step-by-step explanation:
Given that:
Water faucet is turned 5/7 to the right ; then
Water faucet is again turned 1/4 to the right
How far is the water faucet turned ;
Since it is turned towards the same direction during both turning ;
First turning + second turning
5/7 + 1/4
L.C.M of 7 and 4 = 28
[(4*5) + (7*1)] / 28
(20 + 7) / 28
27 / 28
Answer:
c)
Step-by-step explanation:
Can't be b) or d) because you have to substract... from c2, so it's not c2 -... And it has to be c) because in a) you don't have twice the sum of a and b, you only have twice a and than you add b.
So it's c)

Step by step
The correct answer is B) 9 m.
The measure of the sector of circle R is 32π/9 m. The measure of the central angle is 80°. This means that the sector is 80/360 = 2/9 of the circle. The area of a circle is given by A=πr², so the area of the sector is A=2/9πr². To verify this, 2/9π(4²) = 2/9π(16) = 32π/9.
Using this same formula for circle S, we will work backward to find the radius:
18π = 2/9πr²
Multiply both sides by 9:
18*9π = 2πr²
162π = 2πr²
Divide both sides by 2π:
162π/2π = 2πr²/2π
81 = r²
Take the square root of both sides:
√81 = √r²
9 = r
Answer:
C
Step-by-step explanation:
you can make a right triangle from the center of one base to the edge of that circle, and then up to a point on the circumference of the other base
the bases of the triangle would be 2 and 5
so that gives sqrrt 29
