Answer:

30.96 m²

Step-by-step explanation:

In white there are four parts of a circle, so we can split the 12 m in half to show the radius, and then solve to find the area of the full circle.

A = r²

a = (6)²

a = (36)

a = 113.04

Then you find the area of the whole box.

12 x 12 = 144

Then you subtract the area of the circle in white from the area of the whole box.

144 - 113.04 = 30.96 m²

So that’s the area of the shaded region.

A 12-ft ladder leaning against a house makes a 64 degree angle with the ground. Will the ladder reach a window sill that is 10.5

Luba_88 [7]

Answer:

Yes, it will

Step-by-step explanation:

Given

Length of Ladder = 12 ft

Angle = 64

Required

Determine if it'll reach a height of 10.5ft from the base

See attachment for proper illustration.

<em>From the attachment, we want to determine that x be greater than 10.5</em>

Using sin formula:

$Sin\ 64 = \frac{x}{12}$

Multiply through by 12

$x = 12 * sin\ 64$

$x = 12 * 0.8988$

$x = 10.79$ (Approximated)

<em>Since 10.79 is greater than 10.5, then the ladder will reach the window</em>

sin64 = x/12

x = 12* sin64

It took Ivan 7.5 hours to drive 412.5 miles. How fast was he driving?

Tju [1.3M]

Since the question is asking how fast he is driving, we need to find his speed in miles per hour. To do this, you need to divide the amount of miles he drove by the amount of hours it took. When you do 412.5/7.5, you get the answer of 55 miles per hour.

The circle graph shows the result of a survey. In what way is this graph misleading? Explain.

Rashid [163]

Step-by-step explanation:

because the total sum of each percent is 90%

and it must be 100% as it is a full circle
