What is the area of the shaded region plzz help
Aneli [31]

Answer:

78.10 cm^2

Step-by-step explanation:

The area of the shaded region is the area of the rectangle subtracted from the area of the circle.

area of circle = (pi)r^2

area of rectangle = LW

shaded area = area of circle - area of rectangle

shaded area = (pi)r^2 - LW

shaded area = (pi)r^2 - LW

shaded area = (3.14159)(6 cm)^2 - (7 cm)(5 cm)

shaded area = (3.14159)(36 cm^) - 35 cm^2

shaded area = 113.097 cm^2  35 cm^2

shaded area = 78.097 cm^2

Answer: 78.10 cm^2

Heather had to collect insects for her biology project. She was able to collect 225 total insects. She collected 8 times as many
GREYUIT [131]

200 flying insects she catch for her project .

<u>Step-by-step explanation:</u>

We have , Heather had to collect insects for her biology project. She was able to collect 225 total insects. She collected 8 times as many insects that could fly as insects that couldn't fly. That means insects ratio of non-fly to fly is 1:8 .

There are a total of 225 insects , and for every one non fly insect there are 8 fly insects  , Let x be the number of insects that can't fly so:

x + 8x = 225

⇒ x + 8x = 225

⇒ 9x = 225

⇒ \frac{9}{9}x = \frac{225}{9}

⇒ x = \frac{225}{9}

⇒ x = 25

So , Number of fly insects = 8x = 8(25) = 200 . ∴ 200 flying insects she catch for her project .
