Step-by-step explanation:
Find the radius: 19 ÷ 2 = 9.5
4/3 x 22/7 x 9.5 x 9.5 x 9.5 = 3592
3592/3 =
1197.3 (Rounded to 1 decimal place)
Answer: 1197.3cm3
(I have never done area or perimeter of sphere before, but I did for other shapes. This is just my attempt using the methods I did for other shapes by the way)
Answer:
<em> 200cm²</em>
Step-by-step explanation:
Total surface area of the prism = bh + L(s1+s2+s3)
b is the base of the triangle = 15cm
h is the height of the triangle = 8cm
Perimeter of the triangular base = s1 + s2 + s3 = 8+17+15
Perimeter of the triangular base = 40cm
L is the lateral height = 2cm
Substitute the given values into the formula;
Total surface area of the prism = 15(8) + 2(40)
Total surface area of the prism = 120+80
Total surface area of the prism = 200cm²
<em>Hence the total surface area of the prism is 200cm²</em>
All three angles of a triangle add up to 180 degrees.

Subtract 146 to both sides:

So your answer is B.
Answer:
x=29
Step-by-step explanation:
−3(3+x)+4(x−6)=−4
(−3)(3)+(−3)(x)+(4)(x)+(4)(−6)=−4(Distribute)
−9+−3x+4x+−24=−4
(−3x+4x)+(−9+−24)=−4(Combine Like Terms)
x+−33=−4
x−33=−4
Step 2: Add 33 to both sides.
x−33+33=−4+33
x=29
