Answer:
A. 68 units2
Step-by-step explanation:
First of all to solve this problem we have to know the formula to calculate the surface area of the cone
A = area
r = radius = 4
L = 13
π = pi
A = π*r² + π*L*r
we replace with the known values
A = π * (4u)² + π * 13u * 4u
A = 16π u² + 52π u²
A = 68π u²
The surface area of the cone is 68π u²
Answer:
A and c
Step-by-step explanation:
1) Length arc = r*theta
5.11=1*theta. Theta is 5.11 rads
2) Law of cosines is the correct answer
Answer:
(0,-3)
Step-by-step explanation:
( r, theta)
We know that x = r cos theta
x = -3 cos (pi/2)
x = -3 *0 = 0
We also know that y = r sin theta
y = -3 sin (pi/2)
y = -3*1 = -3
The rectangular coordinates are
(0,-3)
Answer:
The last answer D is the answer
The date that Chris will have both training sessions again is May 9.
<h3>How to calculate the date?</h3>
In mathematics, a multiple simply means the product of any quantity. It should be noted that a multiple illustrate to the product of a number given.
In this situation, since Christ has bowling training every 8 days and hockey training every 2 days. The lowest common multiple for 2 and 8 is 8.
Therefore, the next date will be the addition of the day of the training and the number of days that are needed when the lowest common multiple was calculated. This will be illustrated thus:
= May 1 + 8 days
= May 9
The next training is May 9.
