Step-by-step explanation:
Given that,
Radius of cone, r = 8 cm
Slant height of the cone, l = 17.9 cm
We need to find the surface area of a cone. The a cone, its surface area is given by :
Putting the values of r and l in above formula such that,
So, the surface area of a cone is . Hence, this is the required solution.
Answer:
b
Step-by-step explanation:
in order for it to be a function the x values cannot repeat.
in answer b the x value 6 repeats twice therefore it is not a function
Answer:
the answer is d
Step-by-step explanation:
a function is where you have 1 output for every input so you can't have an x value with 2 different outputs
Answer:
B
Step-by-step explanation:
Step 1: Find √11
√11 is between perfect squares √9 and √16
√9 < √11 < √16
3 < √11 < 4
So it is between 3 and 4
Step 2: Evaluate
√11 = 3.31662
Closest dot is B.
Answer:
a) $8.80
b) 40%
Step-by-step explanation:
<u>Part (a)</u>
Given:
- Original price = $22
- Discounted price = $13.20
Original price - discounted price
= $22 - $13.20
= $8.80
<u>Part (b)</u>
percentage = (amount discounted ÷ original price) x 100
= (8.80 ÷ 22) x 100
= 40%
