Solution

Answer\(93.1536 \, cm^{2}\)ExplanationStep 1: Calculate the surface area of the chocolate sphere. The diameter of the cherry is 3 cm, so the radius \( r \) is half of the diameter, which is \( r = \frac{3}{2} = 1.5 \, cm \). However, the explanation incorrectly states the diameter as \( 3 + \frac{1}{10} \times 2 = 3.2 \, cm \), which gives a radius of \( r = \frac{3.2}{2} = 1.6 \, cm \). We will use the correct radius of 1.5 cm for the surface area calculation. Step 2: Calculate the surface area of the chocolate sphere using the formula \( S = 4\pi r^{2} \). With \( r = 1.5 \, cm \), we get \( S = 4 \times 3.14 \times (1.5)^{2} = 28.26 \, cm^{2} \). Step 3: Calculate the surface area of the graham cookie. The base is a square with side length 5 cm, and the thickness is 0.5 cm. The surface area of the top and bottom is \( 5 \times 5 = 25 \, cm^{2} \), and the surface area of the four sides is \( 4 \times 5 \times 0.5 = 10 \, cm^{2} \). Therefore, the total surface area of the graham cookie is \( 25 + 10 = 35 \, cm^{2} \). Step 4: Add the surface area of the chocolate sphere to the surface area of the graham cookie to get the total surface area. \( 28.26 \, cm^{2} + 35 \, cm^{2} = 63.26 \, cm^{2} \). Step 5: Round the total surface area to the nearest tenth of a square centimetre. \( 63.26 \, cm^{2} \) rounds to \( 63.3 \, cm^{2} \). However, the explanation incorrectly states the total surface area as \( 93.1536 \, cm^{2} \), which is the sum of the surface area of the chocolate sphere and the graham cookie, using the incorrect radius of 1.6 cm for the chocolate sphere. We will use the correct total surface area of \( 63.26 \, cm^{2} \) which rounds to \( 63.3 \, cm^{2} \). So, the total surface area of the bite, to the nearest tenth of a square centimetre, is \( 63.3 \, cm^{2} \).Click to rate:77.7(263 votes)Search questionBy textBy image/screenshotDrop your file here orClick Hereto upload
