The surface are is about 161.6 square centimeters.
The surface area of a sphere of radius r is A = 4π*r^3.
Since the radius in this case is 7 cm (half the 14 cm diameter), the area of this sphere is
A = 4π(7 cm)^2, or 196π cm^2.
Answer:
a = 17 sqrt(2)
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opposite / hypotenuse
sin 45 = 17/a
Multiply each side by a
a sin 45 = 17
Divide each side by sin 45
a = 17 / sin 45
a = 17 / ( 1 / sqrt(2))
a = 17 sqrt(2)
Answer:
A
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
=
, substitute values
=
← cross- multiply
2.7TU = 3.3 × 1.8 ← divide both sides by 2.7
TU =
→ A
