Answer:

A) 43.96 cm (Circumference)

B) 153.86 square cm (Area)

A) 62.8 ft (Circumference)

B) 314 square ft (Area)

Step-by-step explanation:

3. Radius 7 cm

7*2=14 (Find the diameter)

14*3.14= 43.96 cm (Circumference)

7*7=49 (Find the square of radius)

49*3.14 = 153.86 square cm (Area)

4. Diameter: 20 ft

20*3.14 = 62.8 ft (Circumference)

20/2=10

10*10=100

100*3.14= 314 square ft (Area)

Point R is located at (3,2) and point S is located at (8,15) . What are the coordinates of the point that partitions the direct

faltersainse [42]

The coordinates of the point can be solve using the fomula:

x = x1 + r( x2 - x1 )
y = y1 + r( y2 - x1)
where r is the ratio that partitions the segment
x = x1 + r( x2 - x1 )
x = 3 + 1/3( 8 - 3 )
x = 3 + 1/3( 5 )
x = 14/3
y = y1 + r( y2 - x1)
y = 2 + 1/3( 15 - 2)
y = 2 + 1/3( 13 )
y = 19/3
so the coordinate is ( 14/3 , 19/3 )

Answer:

Step-by-step explanation:

180 -40 - 90 = 50

I don't remember the name of the type of angle, but since that one angle is 50 the other side is also 50.

180 - 90 - 50 = 40

Tell me if I am wrong.
