If the area of a circle is
7.7 cm2, what is the
circumference of the
circle? (I need a step-by-step answer for further understanding please!!)
Answer:
Since area =7.7
[tex]area = \frac{22}{7} {(r)}^{2} \\ {(r)}^{2} = 2.45 \\ r = 1.57[/tex]
Then the circumference is
[tex]c = 2pi\times r \\ = 2 \times 3.14 \times 1.57 \\ = 9.859[/tex]

Find the distance between the two points in simplest radical form.
(-2, 1) and (-8, 9)
Answer:
10
Step-by-step explanation:
d = √(x2 - x1)² + (y2 - y1)²
d = √(-8 - -2)² + (9 - 1)²
d = √(-6)² + (8)²
d = √(36) + (64)
d = √100
d = 10

3 ft Find the outer perimeter of this figure. Round your answer to the nearest hundredth. Use 3.14 to approximate it. 4 ft 5 ft 5 ft P = [?] ft
Answer:
perimeter = 19.42 ft
Step-by-step explanation:
perimeter of semi circle = 6π/2 = 9.42
perimeter of cone = 5 + 5 = 10
10 + 9.42 = 19.42 ft
The outer perimeter of the semicircle will be 9.42 feet.
What is a circle?It is the centre of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.
The radius of the semicircle is 3 feet.
Then the outer perimeter of the semicircle will be
Perimeter = πr
Perimeter = π x 3
Perimeter = 9.42 feet

Tommy bought a total of 20 game cards some of which cost $0.25 each. Of tommy spent $4.20 to buy these cards how many cards of each type did he buy
The question is incomplete:
Tommy bought a total of 20 game cards some of which cost $0.25 each and some of which cost $0.15 each. If Tommy spent $4.20 to buy these cards,how many cards of each type did he buy?
Answer:
He bought 12 cards that cost $0.25 and 8 cards that cost $0.15.
Step-by-step explanation:
From the information given, you can write the following equations:
x+y=20 (1)
0.25x+0.15y=4.20 (2)
First, you can solve for x in (1):
x=20-y (3)
Now, you can replace (3) in (2):
0.25(20-y)+0.15y=4.20
5-0.25y+0.15y=4.20
5-0.10y=4.20
5-4.20=0.10y
0.80=0.10y
y=0.80/0.10
y=8
Finally, you can replace the value of y in (3) to find x:
x=20-y
x=20-8
x=12
According to this, he bought 12 cards that cost $0.25 and 8 cards that cost $0.15.
