Find the exact or approximate area of the shaded region

Mathematics
1 answer:
Lana71 [14]3 years ago
7 0

Answer: 18.24 cm^2

Step-by-step explanation:

the two 135 degree angles indicate that the third angle (the one with the shaded region) is 90 degrees, which means that the shaded region is within 1/4 of the circle.

1. In order to find the area for that 1/4 region, you would have to find the area of the circle and divide it by 12

[r^2(3.14)]/4      pi is substituted by 3.14, and the radius is 8.

50.24 is the area of 1/4 of the circle.

2. Next you'd have to find the area of the triangle formed by the shaded region, and subtract the triangle from the area of the 1/4 circle.

the triangle is an isoceles triangle with two sides each valuing at 8cm, so to find the area of the triangle you would multiply the two sides (or square them since they're the same number) and divide by two

this means the triangle is 32 cm^2

3. we can subtract the 1/4 circle (50.24) by the area of the triangle (32) to get the area of the shaded region, which is <u>18.24 cm^2</u>

Joe is finding the length of a rectangular prism. The volume of the prism is 204 ft3. The width is 3.5 ft, and the height is 5 f
zmey [24]

Answer:

B. He added 3.5 and 5 when he should have multiplied them.

Step-by-step explanation:

Let's observe Joe's steps:

- V = lwh

- 204 = 3.5 * (5) * l

Here, * means to multiply, so we're supposed to multiply 3.5 to 5, which would give you the answer 17.5. Unfortunately, look what Joe got: he obtained the value of 8.5, and if we observe, 3.5 + 5 = 8.5.

That's how we know that Joe added instead of multiplied, as he should have done. Thus, the answer is B.

What is the formula for lineal equetion​
Gwar [14]

Answer:

y=mx+c

Step-by-step explanation:

A linear equation means the equation of straight line.

The formula for equation of straight line in slope intercept form is y=mx+c

where, m is the slope of line and c is the y intercept

The formula for equation of straight line in double intercept form is x/a+y/b=1

The formula for equation of straight line in normal form is xcos α + y cos α=p

There are more formulas bur assuming you are asking for the general representation of the straight-line equation, it is y=mx+c.
