The surface area of the cone is calculated to the nearest tenth as: 173.4 cm².
<h3>What is the Surface Area of a Cone?</h3>
Surface area of a cone = πr(r + l),
Given the following:
- Radius (r) = 4 cm
- Slant height (l) = 9.8 cm
Plug in the values
Surface area of the cone = π × 4(4 + 9.8)
Surface area of the cone = 173.4 cm²

A) Original price : y =10.x
Cheaper brand : y = 7x
The original box is $3 more than the cheap one. Proof:
Suppose 1 box is bought of each (x=1),original will cos10 & the cheaper $7
b) Each time he buys a cheap brand he save $3 ($10-$7), on 5 cheap boxes, he would save $3 x 5 boxes = $15
Step 1: Add up all the scores.
Step 2: count the number of scores.
step 3: divide the sum of the scores by the number of scores themselves.
step 4: The answer is 26 points.
