Answer:

The area of circle is 94.985 m², therefore the correct option is 3.

Step-by-step explanation:

The area of a circle is

A=\pi r^2

Where r is the radius of the circle.

From the given figure it is clear that the diameter of the circle is  11 m. So, the radius of the circle is

r=\frac{11}{2}=5.5m

The radius of the circle is 5.5 m.

The area of the given circle is

A=\pi (5.5)^2

A=(3.14)\times (5.5)^2

A=94.985

The area of circle is 94.985 m², therefore the correct option is 3.

B. A 50A by 35ft residential
MariettaO [177]

Answer:

1.13 food per square feet

Step-by-step explanation:

Given

Dimension: 50ft by 35ft

Servings = 1975

Required

Determine the amount per servings

First, we calculate the area.

Area = 50ft * 35ft

Area = 1750ft^2

Next, we calculate the amount per square foot.

This is:

Rate = \frac{Serivings}{Area}

This gives;

Rate = \frac{1975}{1750}

Rate = 1.13

The coordinates of A and B are (3k, 8) and (k, -3) respectively. Given that the gradient of the line segment AB is 3, find the v
Vladimir [108]

Step-by-step explanation:

gradient = slope or several other words.

it describes how strongly a line (or tangent to a bent curve) is going up or down or ... if it is changing at all.

it is represented by the ratio

(y coordinate change / x coordinate change)

when going from one point on the line to another.

in our case, when going from A to B we have

x changes by -2k (from 3k to k).

y changes by -11 (from 8 to -3).

so, the gradient or slope is

-11/-2k = 3

11/2k = 3

11 = 3×2k = 6k

k = 11/6

A = (33/6, 8) = (11/2, 8)

B = (11/6, -3)
