Answer all of them for a and brainlest 1) find the surface area of a sphere with a radius of 8 cm. a 267.9 cm b 803.8 cm c 2143.6 cm d 2010. cm 2) find the surface area of a sphere with a radius of 4 ft. a 452.2 m b 150.7 m c 113.0 m d 904.3 3) find the volume of a sphere with a radius of 4 ft. a 33.5 ft b 67.0 ft c 267.9 ft d 803.8 ft 4) for the pair of solids, find the value of the variable a 3 cm b 18 cm c 16 d 2 cm 5) for the repair of solids, find the value of the variable a 12 mm b 48 m c 20 mm d 3 mm 6) a pyramid has a height of 5 in. and a surface area of 90 in. find the surface area of a similar pyramid with a height of 10 in. round to the nearest tenth. if necessary. a 360 in b 180 i c 22.5 in d 3.6 in 7) a rectangular prism width of 92 ft and a volume of 240 ft. find the volume of a similar prism with a width of 46 ft. round to th nearest tenth, if necessary. a 30 f b 40 ft c 60 ft d 120 ft

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841

b. x + 1
