Answer:
it is 23. always remember it's supposed to add up to 180. So add up all your numbers and subtract the total from 180 to get your answer
Answer:
l= 234/r
Step-by-step explanation:
Given data
Surface area of cone=734.76 square meters.
The formula for the lateral surface area is
S.A=πrl
substitute the surface area
734.76 = 3.14*r*l
734.76/3.14=rl
234=rl
l= 234/r
Hence, with a value for r, the expression for the slant height l is given as
l= 234/r
Calculate area of the triangle:
Height x Lenght of base x 1/2
4cm x 6cm x 1/2 = 12 square cm
Now multiply the are with the length of the prism:
12 square cm x 10 cm = 120 cubic cm
Its 10. Parenthesis mean to multiply.
