Answer/Step-by-step explanation:
Given:
m<A = 115,
m<B = 78,
m<C = 35,
✔️m<1 = 180 - m<A (angles on a straight line/supplementary angles)
m<1 = 180 - 115 (substitution)
m<1 = 65°
✔️m<2 + m<1 + m<B = 180° (sum of interior angles of a triangle)
m<2 + 65 + 78 = 180
m<2 + 143 = 180
m<2 = 180 - 143 (substitution property of equality)
m<2 = 37°
✔️m<3 = 180° - m<B (supplementary angles)
m<3 = 180 - 78
m<3 = 102°
8*3+6-2
8*3=24
24+6=30
30-2=28
8*3+6-2=28
To evaluate (find the value of this expression), you will evaluate what is in the middle set of parentheses first. You can evaluate powers at the same time as if the are outside the parentheses. Follow this with the outside parenthesis.
Next evaluate all multiplying or dividing left to right.
Finally, add or subtract left to right.
2[3(4^2 + 1)] - 2^3
2[3 x (16+1)] - 2^3
2[3 x 17] - 8
2(51) -8
102 - 8

Answer:
the volume of the sphere is 507.78981 cm^3
Step-by-step explanation:
The computation of the volume of the sphere is given below:
Given that
The Diameter is 9.9 cm
So, the volume of the sphere is
= 4 ÷ 3 ×π × r^3
= 4 ÷ 3 × 3.14 × 9.9 ÷ 2^3
= 4 ÷ 3 × 3.14 × 4.95^3
= 507.78981 cm^3
Here r denotes the radius
And, the radius would be comes by dividing the diameter from 2
Hence, the volume of the sphere is 507.78981 cm^3
