Answer:
B
Step-by-step explanation:
To calculate the area of this triangle we can use the Heron’s formula
Mathematically we have the Heron’s formula as;
A = √s(s-a)(s-b)(s-c)
where s = (a + b + c)/2
Thus, s = (15 + 12+ 10)/2 = 18.5
a = 15, b = 12 and c = 10
Plugging these values into the equation, we have
√18.5(18.5-15)(18.5-12)(18.5-10)
= √18.5(3.5)(6.5)(8.5)
= √ 3,577.4375
A = 59.8116
which is approximately 59.8 square units

Answer:
0.905 in
Step-by-step explanation:
Parameters given:
Volume of cone, V = 3.6 in³
Height of cone, h = 4.2 in
Although the diagram is not shown, this problem can be solved.
The volume of a cone is given as:
V = ⅓ * π * r² * h
r is the radius of the base of the cone
We can find r.
3.6 = ⅓ * π * r² * 4.2
3.6 = 4.399 * r²
=> r² = 3.6 / 4.399
r² = 0.8184
=> r = 0.905 in
The radius of the base of the cone is 0.905 in.
As x approaches 2 from the left, y approaches 2+3 (or 5) from below. But because of the open parenthesis at the right of (-infinity, 2), as well as the jump in y value (from 5 to 1) at x =2, the limit does not exist.
