The surface area of the cone is calculated through the equation,
A = πr² + πrl
where r is the radius and l is the slant height. Substituting the known values to the equation,
43.75π = π(5 cm)² + π(5 cm)(l)
l is 3.75 cm. Thus, the slant height of the cone is 3.75 cm.
6/11(5/6)+2/11(5)
=5/11+10/11
=15/11
Answer:
55 miles
Step-by-step explanation:
11 miles = 45 min
speed = distance/time
speed = 11/45
speed = 0.2444 miles/min
for 225 min, speed is same
distance = speed * time
= 11/45 * 225
=55 miles
60+-90x would be equivalent.
Since the graph is a linear function, we're going to use the slope formula solve this:
Note I am replacing m with k

Inserting 2 points from the graph, let's use (1,8) and (2,16).

k=8
