The volume of a sphere is 2,240 yd^3. What will be the new volume in the dimensions are multiplied by 1/4?
Veseljchak [2.6K]

Answer:

34.98yd^3

Step-by-step explanation:

Volume of a sphere V=4/3πr3

Where V = 2240yd^3

π = 3.14

2240 = 4/3×3.14×r^3

2240 = 4.1866r^3

r^3 = 2240/4.1866

r^3 = 534.784

r = ( 534.784 )^1/3

r = 8.1169

Since each dimension is to be multiplied by 1/4

Hence, 1/4×8.1169

r = 2.029.

New volume will be

V = 4/3×3.14×2.029^3

V = 4/3×3.14×8.3558

V = 34.98yd^3.

In triangle pqr, rs=4 and qs=6. find ps
Svetradugi [14.3K]

Answer:

PS=2\sqrt{6}

Step-by-step explanation:

we are given triangle as

we know that

triangle PRS and triangle PQS are similar

so, the ratios of their sides must be equal

we get

\frac{RS}{PS}=\frac{PS}{QS}

now, we are given

RS=4

QS=6

we can plug it

\frac{4}{PS}=\frac{PS}{6}

PS^2=6\times 4

PS^2=24

now, we can solve for PS

PS=2\sqrt{6}
