Answer:

140.37 in²

Step-by-step explanation:

C = 2πr

42 = 2πr

21 = πr

r = 21/π

A = πr²

A = π × (21/π)²

≈ 140.37 in²

Graph the line whose y-intercept is - 9 and whose x-intercept is 5.

Nostrana [21]

Answer:

y=1.8x-9

Step-by-step explanation:

if they are intercepts so the x/y will be zero, so in y intetceot the x is zero, and in the x itercept the y is zero.

0,-9

5,0

we calculate the slooe / rise

-9-0/0-5 = 1.8

we then use this formula

y-y1=rise(x-x1)

y-0=1.8(x-5)

y=1.8x-9

Marco is making a kite, using sticks for its diagonals. One stick is 2 feet long and the other is 3 feet long. How much material

Marat540 [252]

Answer:

Marco will need $3\ ft^{2}$ of material to make the kite

Step-by-step explanation:

we know that

To know how much material Marco will need to make the kite, the area must be calculated.

Remember that the area of the kite is equal to

$A=\frac{1}{2}[d1*d2]$

where

d1 and d2 are the diagonals of the kite

we have

$d1=2\ ft$

$d2=3\ ft$

substitute

$A=\frac{1}{2}[2*3]=3\ ft^{2}$
