Find the area of the shape.
mars1129 [50]

Answer:

<u>27π units²</u>

Step-by-step explanation:

The rest of the question is the attached figure.

This shape represents (3/4) of a full circle.  

So, find the area of a full circle with radius 6 units, then multiply the result by 3/4 to obtain the area of the given shape.

Area of full circle = π r²

So, Area of full circle = π(6)² = 36π units²

Then the area of the given shape is = <u>(3/4)(36π) = 27π units²</u>

Mice21 [21]

Answer:

Part 1) Helen's age is 32 years old and Jane's age is 24 years old

Part 2) 13 twenty-dollar bills

Step-by-step explanation:

Part 1) Helen is 8 years older than Jane. Twenty years ago Helen was three times as old as Jane. How old is each now and what is the equation?

Let

x----> Helen's age

y---> Jane's age

we know that

x=y+8 ----> equation A

(x-20)=3(y-20) -----> equation B

substitute equation A in equation B and solve for y

(y+8-20)=3(y-20)

y-12=3y-60

3y-y=60-12

2y=48

y=24 years

Find the value of x

x=y+8

x=24+8=32 years

Part 2)

Let

x-----> the number of five-dollar bills

y----> the number of twenty-dollar bills

we know that

5x+20y=305 -----> equation A

y=x+4 ------> x=y-4 ------> equation B

substitute equation B in equation A and solve for y

5(y-4)+20y=305

5y-20+20y=305

25y=325

y=13 twenty-dollar bills

Find the value of x

x=y-4

x=13-4=9  five-dollar bills
