Please help!! circles combos are too hard​

Mathematics
1 answer:
malfutka [58]2 years ago
7 0

Answer:

56 + 53pi

Step-by-step explanation:

<u><em>Area of small circles:</em></u>

diameter of small circle: 4cm

forumla to find area of circle: A = pir^2

r is radius = half of diameter -> d/2 = 4 / 2 = 2cm

A = pi (2cm)^2

A = pi (4cm)

A = 4pi

<u><em>Area of large circle:</em></u>

diameter of small circle: 4cm

forumla to find area of circle: A = pir^2

r is radius = half of diameter -> d/2 = 14 / 2 = 7cm

A = pi (7cm)^2

A = pi (49cm)

A = 49pi

<u><em>Area of rectangle:</em></u>

Area = width x length

Area = 14cm x 4cm

Area = 56cm

<u><em>Add all three areas:</em></u>

Area of rectangle + large circle + small circle

56cm + 49pi + 4pi = 56cm + 53pi

Trevor and Marissa sell T-shirts at the craft fair Marisa has six fewer T-shirts then Trevor and together they have a total of 2
avanturin [10]
M + t = 26
m = t - 6

t - 6 + t = 26
2t - 6 = 26
2t = 26 + 6
2t = 32
t = 32/2
t = 16 <== Trevor has 16

m = t - 6
m = 16 - 6
m = 10...and Marissa has 10

What is the perimeter, P, of a rectangle that has a length of x +8 and a width of y - 1?
Dafna1 [17]

Answer:

P=2x+2y+14

Step-by-step explanation:

Perimeter (P)of a rectangle = 2( l+b)

where l is the length and b is the width of the rectangle .

Here, l= x+8

and, b= y-1

so, P = 2{(x+8)+(y-1)}

= 2( x+8+y-1)

= 2(x+y+7)

=2x+2y+14

A chess club plans to sell water to raise $425 and they already have 175, if they sell water bottles for 8$ each, at least how m
alisha [4.7K]

Answer:

32 water bottles

Step-by-step explanation:

8x=425-175

425-175=250

250 is how much more they need.

8x=250

x=31.25

You can't have half of a bottle... so round up to at least 32 water bottles
