The surface are of the right cone is 176 sq.units. Option A) is the correct answer.
<u>Step-by-step explanation</u>:
<u>step 1</u> :
Radius of the cone, <em>r = 4</em>
Height or length of the cone,<em> h = 10</em>
<u>step 2</u> :
Total surface area of right cone = πrh + πr^2
= (π
410) + ( π4^2)
= 40π + 16π
= 56 π = 563.14
= 176 sq.units
900 because look 51 * 71 = 9187 so then just after simplify
The line rising to the right has equation y = x + 2
and the other one has equation y = -x + 4
the lines are solid so the inequalities will be <= or >=
in both case the shading is below so the sign is <=
also x and Y values are both positive
so the answer is choice C
The answer:
-7 3/4, -7.6, -6 7/8, 32/5, 6.9
Answer:
O A. PQ = SU
Step-by-step explanation:
When two triangles are congruent then by CPCTC,
their corresponding parts ( angles and sides ) must be congruent.
In triangles PQR and STU,
Side PQ, QR and RP are corresponding to the sides ST, TU and US respectively,
Also, angles P, Q and R are corresponding to angles S, T and U respectively.
Here, Δ PQR ≅ Δ STU,
Thus, by the above property,
PQ ≅ ST, QR ≅ TU and RP ≅ US,
∠P ≅ ∠T, ∠Q ≅ ∠T and ∠R ≅ ∠U
