Answer:
πr^2 + L×W
Step-by-step explanation:
we have to find the two areas then we add to get the total area.
<1 = 123
60 + 63 = 123
180 - 123 = 57
180 n- 57 = 123
Triangle angle-sum theorem
Alternate exterior angles theorem (?)
Same side interior angles theorem
idk what the last one is about sorry
hope this helps
The volume of a cone is 1/3 the volume of the cylinder so,
V of Cylinder = 144*3.14 = 452.16
V of cone = 1/3 * 452.16 = 150.72 or 48π
Hope this helps :)
Answer:
10.50
Step-by-step explanation:Harold deposited $70 in an account earning 5% interest compounded annually. To the nearest cent, how much interest will he earn in 2 years? Use the formula B=p(1+r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
