We need to solve for the area of the sector.

A = n/360 * π * r²
A = 85/360 * 3.14 * 5²
A = 0.2361 * 3.14 * 25
A = 18.5347 

Answer is C. 18.5 square meters.

hodyreva [135]

Answer:

50.2 square cm

Step-by-step explanation:

Diameter = 8 cm

Radius = 8/2 = 4 cm

area \: of \: circle = \pi {r}^{2}  \\  = 3.14 \times  {4}^{2}  \\  = 3.14 \times 16 \\  = 50.24 \:  {cm}^{2}  \\  = 50.2 \:  {cm}^{2}

The stream of water from a fountain follows a parabolic path. The stream reaches a maximum height of 12 feet, represented by a v
tia_tia [17]

Answer:

y=-3/16(x-8)^2+12

Step-by-step explanation:

Refer to the vertex form equation for a parabola:

y=a(x-h)^2+k where (h,k) is the vertex.

Therefore, we have y=a(x-8)^2+12 as our equation so far. If we plug in (16,0) we can find a:

0=a(16-8)^2+12

0=64a+12

-12=64a

-12/64=a

-3/16=a

Therefore, your final equation is y=-3/16(x-8)^2+12

Perimeter of rectangle = all sides added
= 3+3+7+7 =20


volume of sphere = 4/3 x π x r(cubed)
= 4/3 x π X 4(cubed)
= 268.08257

area of triangle = base x height / 2
= 5 x 6 / 2
=30/2 =15

volume of pyramid = base height x base width x height / 3
= 300

side of triangle ---> use Pythagoras theorem so a(squared) + b (squared) = c(squared)
4(squared) + 3(squared) = c(squared)
16 + 9 = c(squared)
25 = c(squared)
c = 5
