Question

Several different cheeses are for sale. The cheese comes in wedges

Answer 1

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/$360^{o}$)$\pi$$r^{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/$360^{o}$)$\pi$$r^{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 $cm^{2}$.
