Answer: OPTION C (119π cm²)
Step-by-step explanation:
Yon can use the following formula for calculate the surface area of a cone:
Where r is the radius and l is the slant height.
Based on the figure shown attached, you have that:
Therefore, when you susbtitute these values into the formula shown above, you obtain that the surface area of the cone is:
cm²
Answer:
You do 2 times 5x, the simplify.
Answer:
10% discounted
Step-by-step explanation:
500× X = 450
while X is the sale price
so we solve for X
(500X)÷500 = 450 ÷ 500
X = 0.9
then we turn that into percentage
0.9 × 100 = 90%
finding the discount percentage
100% - 90% = 10%
Tan is opposite÷ adjacent.
So tan(d) = 7÷24. It is already in the simplest form.
