Question 1. find the surface area of the square pyramid below.
question 2. find the surface area of the figure below.
question 3. find the surface area of the figure below.

see explanation

Step-by-step explanation:

(1)

SA = area of square base + area of 4 congruent triangular faces

     = (3.5 × 3.5) + (4 × × 3.5 × 10 )

     = 12.25 + 70

     = 82.25 in²

(2)

SA = area of circular base + area of curved surface

[ area of curved surface = πrs, r is the radius and s the slant height ]

SA = π × 2² + π × 2 × 6 = 4π + 12π = 16π ≈ 50.27 m²

(3)

SA = area of circular base + area of curved surface

[ note diameter = 19, hence r = 9.5 ]

SA = π × 9.5² + π × 9.5 × 17 = 90.25π + 161.5π = 251.75π ≈ 790.90 cm²

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
