Several different cheeses are for sale. The cheese comes in wedges
Tpy6a [65]

Answer:

39.30 cm^{2}

Step-by-step explanation:

The area of the top surface of the wedge is the same as the area of a sector.

Area of a sector = (θ/360^{o})\pir^{2}

where: θ is the central angle, and r is the radius.

Given that: central angle = 45^{o}, radius = 10 centimetre.

Area of the top surface = Area of a sector = (θ/360^{o})\pir^{2}

                                      = \frac{45^{o} }{360^{o} } x \frac{22}{7} x (10)^{2}

                                      = \frac{1}{8} x \frac{22}{7} x 100

                                      = 39.2857

                                     = 39.30 cm^{2}

The area of the top surface of the wedge is 39.30 cm^{2}.

A tree 7 ft tall grows an average of 6 in. each year. Which equation models the tree’s height h after x years?
Vesna [10]
The initial height of the tree = 7 ft

Each year the tree grows 6 in.   6 in = 6 / 12 = 0.5 ft

So the tree grows 0.5 ft every year.

After x years, the tree would have grown extra = 0.5*x =0.5x

So the height of the tree would be = Initial height + extra height grown

= 7 + 0.5x

h = 7 + 0.5x

Model is    h = 7 + 0.5x, 

where h = height of the tree in feet after x years. 

Hope this explains it.
